Vintage Acoustic Guitar & Vintage Electric Guitar


Vintage Acoustic Guitar & Vintage Electric Guitar


There are many people out there with a vintage acoustic guitar or vintage electric guitar that really don't know much about what they got. They don't have a clear idea what their antique guitar is worth or even the age or where to look to find out this information or even the value of the information they find.

Well, you could always go to your local music store and get a estimate. You may learn a few things there. But, What do you know about their background and expertise? about their honesty? Well without saying too much negative about the local music stores, I will just say most of them are not experts in this field and probably are basing quotes on local pricing values and their limited knowledge, Not qualifying them as a expert.

There is also books! and websites! If you plan on using a book or website, most importantly look at the year it is published. Old information and old price estimates or quotes is about worthless. The older the more useless, Because the vintage acoustic guitar and vintage electric guitar are like classic and antique cars. The value is based on many different factors. To begin with the year, the make, and the model. Then of course, is this a limited number or limited edition, or special version. Is this a special order item or mass produced or a small production or limited number quality.

And the Quality, Of course the antique guitar closer to perfect condition and like new, the more valuable in most eyes. But, on the other hand, a antique guitar in original condition such as original parts and paint and scratches, scuffs, pings, dents, etc would be worth much more than one that had been restored, repaired and repainted to look like new. Even worse would be updating the parts to new type or something other than OEM (Original Equipment Manufacturer) It is usually worth more 100% original or as close as possible. Keep the instrument original!

Most important factor in determining value is the demand. No matter the condition or age or other qualities, If there is not a demand for the vintage acoustic guitar and vintage electric guitar then the value is down no matter the age or rareness or other factor or quality. I has to be a vintage guitar that is in demand, one that people are willing to pay for! Either because of actual value or perceived value due to demand! It is worth what someone is willing to pay! Based on these many factors and what part of the United States you are in or what part of the World you are in. And the value or perceived value there!

So, How do we know? Like classic and antique cars, All these factors are broken down and took into consideration and put in book form. These books are like a car blue book, not precise, especially for the older, more rare, and more in demand, etc. But the book is just a estimate based on the market value and sometimes the location too, Just to give a starting point and a ball park value or perceived value! It really pays to use the book as starting point and then do your homework! Do all the research so you will know exactly what you got! and what it is worth! whether you are buying or selling you don't want to find out later that you didn't make a fair deal, because you didn't know or take the time to do your homework. Knowledge is power!

Carver Amplifiers - Are Carver Amps The Best?

Musicians and audiophiles know that the quality of your equipment can mean the difference between greatness and just barely getting by. The fidelity and quality of the sound that your equipment is able to produce and the higher-end your speaker equipment is, the more crisp and clean the sound of your music. It's important for anyone who appreciates only the best in sound equipment to know what's out there and available, and just like in many other areas in life, sometimes the classics are still the best. Vintage-era Carver Audio equipment is a highly sought after treasure by those involved in sound production, but why? What makes the equipment such a commodity in the audiophile community, and why might you want some for yourself?

The founder of the Carver Corporation, Bob Carver, was an extremely talented engineer who is most famous for designing the most powerful consumer audio amplifier available in the early 1970's. His innovation and invention in the realm of commercial audio continued to drive forward and produce some of the most famous pieces of audio technology to come out of America. In the most famous incidents of his career, he was accepted two seperate challenges to duplicate the sound of superior and much more expensive audio equipment at a fraction of the cost. Despite being unable to examine the design or even open the lid of the equipment he was duplicating, Carver Audio managed to succeed both times. Eventually, he created the still amazing Silver Seven and it's later models, which sold for 1/40th of the price of amplifiers of the same quality sound.

Carver Audio products from the 1970's and 1980's are still highly sought after pieces of equipment. Carver audio equipment from this vintage era included technology that is still in use today, the foundations of modern audo technology. Noise reduction correlation, sonic holograhy, more sensitive and discerning FM and AM tuners, all are features of Carver Audio stereos and amplifiers that were leading in their field, and in some cases the literal inventors of the technology. The quality that is packed into each piece of Carver equipment is undeniable, making it a true collector's item for people interested in the best quality of sound.

There are any number of websites with information about the various Carver Audio (and its ancestor company Sunfire) products, and also sites to buy or sell such equipment. Now that you understand more about the Carver difference, you should take time to explore the possibilities, and narrow down the equipment you are interested in to what would best fit your needs. There's a wide range of very high quality speakers, amplifiers, and stereo products that are still available from the golden era of sound innovation, perhaps it's time to make some of it yours.

So are Carver Amplifiers (carver amps) the best? You decide!

Vintage Car Speakers

Music is the food for soul that arms us against all the distress and disasters that the world threatens us with. The dryness of urban life and the speed and the hazards of day to day living build inside us a thirst for a fresh breeze where we can breathe freely. But where is the time when we can indulge in something that the heart desires! We are always in a hurry. The extreme pressure and tension of work and other petty matters make us forget our own lives. After all, we are not machines, but human beings.

That is the feeling and philosophy that initiated the incorporation of music systems inside a car. Even within the very busy schedule of your daily life, you may spend a few casual moments while traveling and while driving your car. Your car becomes the only place where you can relax and where you can taste the real flavor of life. This is the realization that led the Galvin Manufacturing Corporation to install a radio inside cars. Before that people used to carry their own domestic music system or radio system inside the car for pure fun and relaxed entertainment. The oldest form of car stereo speakers came to the market as Motorola 5T71. That was the first commercial form of car radio. This was priced in the range of $110 to $130.

The popularity of this model encouraged the original manufacturer and some others to develop the car stereo speaker system. To touch the popularity of Motorola at that time many companies introduced same sounding products like Victorola, and Radiola. And the vintage car music system as the form of jukeboxes came to the market as Rockola. Even in other spheres such as the film industry, the craze became contagious and they adopted the name Moviola for a film-editing machine.

The wind of change reached the international market. In 1932 a German company named Blaupunkt installed their first old form of car stereo speakers inside a Studebaker. In 1952 Blaupunkt became the first company again to install an FM receiver inside a car. This became another milestone in the development of car stereo speakers into its modern forms and specifications.

The vintage car stereo speakers used to use low configuration and low capacity models of transformers, vibrators, capacitors and amplifiers. With the introduction of 12 volt battery cars, the capacity of the fitted music system also increased. This saw the emergence of Ford's popular 'Town and Country' model. The installation of semiconductors facilitated the advancement from the old forms to the new forms of the car stereo speaker. In 1956 the first modern versions of car speakers hit the market when Motorola fitted a 45 rpm disc player inside a Chryslers car. The old reel to reel system of cassette player also was tried, but its popularity was limited because of its clumsiness. But this also took a step ahead when Philips introduced compact cassette in the market in 1964.

The vintage car stereo speakers were the simple home audio speakers. But as they were not suitable for extreme heat and vibration of the car, modified versions were introduced in the market. Extra audio amplifiers began to be used for high sound quality. The real competition began in 1980s when various manufacturers attempted to produce the loudest or the most extravagant car stereo speaker systems. Wayne Harris developed a vintage model of Cadillac Hearse in 1960 to incorporate three subwoofers of 24 inch and eight of 12 inch. The experimentation with sound quality began in 1990s with leading manufacturers like IASCA invading the market.

Vintage Microphones

Famous Microphones That Have Become Part Of Vintage Microphones

Author: Victor Epand

Microphones have undergone a lot of changes over the years. Some designs stayed and others became a part of vintage microphones. Microphone, popularly known as mike or mic, is one of the primary elements in an audio or music system.



The main job of the mic is to convert sound into an electrical signal. It has a large number of applications as in music production system, telephone, hearing aid, motion picture production, etc.



Earlier, microphones were known as transmitters. In 1978, Thomas Alva Edison made the first commercial microphone. It was a type of carbon microphone. Later, in Bell Laboratories in 1962, a new type of capacitor microphone was invented.



There were a number of microphones which have made their marks over the last few decades. Some of the names went on to create history but now they are a part of the vintage microphones.



-Altec model 647

-American model D76

-RCA KB-1A, MI-11000

-RCA KN-3A, MI-3045

-RCA carbon type 1

-RCA model BK-7, MI-11016

-Amperite model R80L

-Bruno labs RV-3

-General Electric or Westinghouse carbon or condenser microphones

-Remler, Turner, or Jenkins-Adair condenser microphones

-Western Electric carbon transmitter model 369

-Western Electric condenser housing model 9-A

-Turner model 51D

-Western Electric carbon transmitter model 273



The History & Development of Vintage Microphones



The early 1930s saw the movie industry trying out new technology to record musical scores. However, the range of microphones offered was low. In came the MGM Studios, in Culver City, CA, to try out the newly invented cardioid mic made by the Siemens Co, Germany. It was used to make "Naughty Marietta" with the likes of Jeanette McDonald and Nelson Eddy.



Dynamic or condenser microphones were much smaller in size than the Siemens' version of the cardioid mic. There was a constant effort made to reduce the size of the microphones to facilitate its use.



James Cannon of Cannon Electric Co. in Los Angeles, CA, was told to build up a connector for the mic. His creation was a 6 pin connector which later on became the prototype of P-type connector, which turned out to be an instantaneous success. 3 conductor connector for camera cable was made then which put Cannon plug to history from 1929 onwards.



Mason and Marshall of the Bell Laboratories made a blueprint of a tubular microphone in 1939. The design was such that it utilized a single element and acoustical tubes of different sizes. It helped in the pickup of directional music. The tubular design was the forerunner of the modern day mics.



Electret condenser microphone is a part of the vintage microphones as it has a history dating back to 1928. It used polarized wax plates. Bogen offered this type commercially under the name Voltage Velotron. The WWII saw the development of wax electret mikes. The Japanese used it in their field devices. However, they did not become very popular due to their instability.



In 1962-1965 the electret mics got their diaphragm made of a metalized thin foil of mylar or teflon. Sony, in 1968, created the then finest electret condenser microphone. That too has now moved into vintage microphones.

Capacitor Plague

Capacitor plague

Author: himfrxls

The capacitor plague (also renowned as awful capacitors) engaged the prevalent premature malfunction of certain emblems of electrolytic capacitors utilised in diverse electronics equipment, and especially in motherboards, video cards, compact fluorescent lightweight ballasts, LCD monitors, and power provision of individual computers.

The first flawed capacitors were glimpsed in 1999, but most of the leveraged capacitors were made in the early to mid 2000s, and while report of their flops (usually after a couple of years of use) has compelled most manufacturers to fix the defects, some awful capacitors were still being swapped or integrated into concepts as of early 2007[update].

An incorrect electrolyte equation inside a defective capacitor determinants the output of hydrogen gas, premier to enlarging or deformation of the capacitor's case, and eventual venting of the electrolyte. In uncommon positions, defective capacitors have even been described to burst or blow up forcefully.

Although up to date constructing methods commonly double-check they vent securely other than blow up, manufacturers have been renowned to omit the key security characteristics that allow this.

A grave worth command difficulty is that good and poor worth electrolytic capacitors will often have equal electric output when freshly fitted.

Only comprehensive accelerated life checking engaging abnormally high ripple currents and high functioning temperatures can identify inferior components. This compares powerfully with most electrical devices constituents which are much less subject to spontaneous malfunction after assembly.

Carey Holzman assertions to be the first reporter to articulate this theme to the public's vigilance and has worked with lawyers to articulate villages from foremost manufacturers.

Faulty capacitors have been discovered out in motherboards as vintage as Socket 7 and have leveraged planks constructed up to the present day. The motherboard businesses assembled and swapped Cast Resin Transformer planks with defective caps located from other manufacturers (see below). The Apple PowerPC line of the iMac G5 computers and some eMac computers'motherboards and power provision were furthermore affected.
A power provide unit with failed capacitors.

While capacitor plague mostly sways desktop computer hardware, this difficulty is by no means constrained to that area. These capacitors can furthermore be discovered in some cameras, mesh swaps, audio equipment, storage disc players, and a kind of other devices.

Some early emblems of exterior climb on aluminum electrolytic capacitors endured from an manifestly alike, but actually distinct difficulty engaging electrolyte leakage. Surface climb on soldering is generally accomplished by first computer display announcing dabs of solder paste up on the issued circuit board, gluing the constituents into place, and then running the board assembly through a reflow baking oven to dissolve the solder.

In an try to double-check more dependable soldering, some manufacturers boost the heat of the reflow, which unidentified to them, damages the rubber closures of the capacitors, initating them to dry out or start to leak after one or two years of operation. Compact equipment for example video camcorders are especially leveraged by this difficulty, in most positions developing uneconomical to repair.

The most prevalent method of identifying capacitors which have failed because of awful electrolyte is visual inspection. Such a capacitor will display one or more of these symptoms:

* Bulging of the vent on the peak of the capacitor. (The 'vent' is the effect marked in the peak of the can. The effect kinds the seams of the vent. It is conceived in order that if the capacitor becomes pressurized it will divide at the vent's seams reassuring the force other than making it explode.)
* In the case of Dell Optiplex GX270s often a "Thermal Event" is brandished in white on a very dark computer display when rebooting.
* Sitting crooked on the circuit board as the base rubber close is push out
* Electrolyte (a crusty dark substance) leaked up on the motherboard from the groundwork of the capacitor
* Venting from the peak of the capacitor, evident as rust-like dark down payments, or a evident aperture in the vent.

Note: the electrolyte is generally damp, not dry. Be very careful not to bewilder electrolyte leakage with the petroleum-based glue (e.g. Evo-Stik) that is occasionally utilised to protected the capacitors to the board.

This glue is a sandy yellow hue but turns darker (towards black) with heat. A dark dark crust up the edge of a capacitor is always glue, not electrolyte. A prevalent effect is corrosion of constituent automatic wrist watch directs enclosed by the glue, premier to leakage present or open-circuit. The occurrence of very dark glue is a certain pointer that the capacitor has overheated due either to interior malfunction or insufficient ventilation.
Failed Tayeh capacitors which have vented through their aluminium tops.

As the capacitor ages, its capacitance declines while its equivalent sequence opposition (ESR) increases. When this happens, the capacitors no longer amply assist their cause of filtering the direct present voltages on the motherboard, and scheme instability results. Some prevalent symptoms are:

* Not rotating on all the time; having to hit reset or try rotating the computer on again
* Instabilities (hangs, BSODs, kernel panics, etc.), especially when symptoms get progressively more common over time
* CPU centre voltage or other scheme voltages fluctuating or going out of kind, likely with an boost in CPU heat as the centre voltage rises
* Memory errors, especially ones that get more common with time
* Spontaneous reboots
* In case of on-board video cards, unstable likeness in some video modes
* Failing to entire the POST, or rebooting before it is completed
* Never beginning the POST; followers rotate but the scheme appears dead

This failed capacitor has blew up and blown its casing off.

Unlike the personal indications which are conclusive clues the capacitors are dropping short, many of the operational indications may be begun by other components, for example a dropping short power provide, dirt clogging a follower, awful RAM, or other hardware problems. Instability, one time the functioning scheme has laden, may display a programs difficulty (such as some kinds of malware, poorly-written apparatus drivers or software), and not a hardware difficulty at all.

If any of these symptoms are accomplished, eliminating the system's case and inspecting the capacitors, especially those around the CPU, may directly identify capacitors as the cause. If there are no personal indications, an oscilloscope may be utilised to analyze the voltage on the capacitors, with unwarranted ripple voltage being a pointer the capacitors are not doing their job.

In some positions, the origin source of the dropping short capacitors is developed espionage gone wrong. Several Taiwanese electrolyte manufacturers begun utilising a thieved equation that was incomplete, and needed components needed to make a stable capacitor.(An anti-corrosion component was not documented, described in comp.risks.)

When a defective capacitor is ascribed, the water-based electrolyte becomes unstable and breaks down, making hydrogen gas. Since these kinds of capacitors are closed in an aluminium casing, the force builds up inside the capacitor until either the flat iron alloy peak of the capacitor begins to angle, or the rubber closing close is push down.

Eventually the force exceeds the power of the iron alloy casing and venting happens, either by blowing out the rubber base of the capacitor, or bursting the tallied iron alloy vent on the peak of the capacitor. When an electrolytic capacitor bursts, consequences can kind from a burst and a hissing disturbance to a little explosion. Venting is normally messy, and the acidic electrolyte should be cleansed off the motherboard to avert farther damage.

IEEE Spectrum enclosed the issue,and subsequent approximated that the difficulty cost US$100 million to fix.
