On Repairing Antique and Vintage Stereos
Antique radios, and Hifi consoles generally refer to tube units built up to the middle 1960's to the late 1970's. The "vintage" era is often referred to as "silver faced." The modern stereos, built from 1980 to the present are actually amplifier/receivers combined with computer circuitry. They do not sound as good, nor are as "user friendly" as the vintage HiFi's/Stereos. By user friendly, I mean you don't have to go through menu after menu to turn set on, set a function, set a volume and play music.
In my opinion, antique, HiFi and silver faced stereos were the best ever made in terms of sound quality and reliability. Design and manufacturer wise, the companies took great pride in their creations. Most have never been repaired and are still functioning today. The ones in need of repair have been either misused (dropped, hooked up incorrectly, water damage, etc.) or stored in attics or basements (temperature and humidity fluctuations adversely affects electronics) when not being used.
Vintage stereos with their large bass speakers and powerful amps were designed to mimic a live musical performance; to give you the visceral feeling the performance was right in front of you. Something has been lost, sound quality wise, in the modern stereos with their surround sound and multiple speakers. It sounds too refined, too processed for me. I like the "raw" sound of the antique/vintage era. It sounds more real.
Repairing the antique/vintage systems is like repairing a '57 Chevy. you can visually trace the wires and troubleshoot the unit without specialized test equipment. Repairing the modern stereos (1980-on) requires specialized test equipment and usually a 100 page service manual. As a result, the vintage stereos are less expensive to repair than the modern stereos. Parts for the vintage units are easier to get now than in the 70's. In the 70's you had to contact the manufacturers, get a price, send in a check and wait a week to two weeks for delivery. Now you can order a part, charge it, and get overnight delivery. Smart repair techs build a stock of commonly used replacement parts, and often purchase used HiFi's at yard sales for parts no longer available.
In conclusion, most antique HiFi's are repairable although you will come across the occasional unit where parts cannot be found. As a last resort, unrepairable consoles can have the turntables and amp sections replaced with more modern pieces instead.
