Frequently Asked Questions
1.Why repair my old stereo when I can buy new for $200.00?
Remember the adage: YOU ONLY GET WHAT YOU PAY FOR! Today’s systems just aren’t what they
used to be unless you’re purchasing the higher end models and I don’t mean the receiver that costs
$200.00 either. The stereos of yesteryear were big, built to last and above all else reliable. Repairing
something ‘old’ may seem crazy when you can buy a new item like a DVD player for $19.99 and new
speakers for about $29.99 as well as a complete ‘surround sound’ stereo system for the price of a tank of
gas! But what will that get you? New products from names no one has ever heard of are bursting on the
market everyday with prices that are simply too low to believe! I do not know about you, but before I
plunk down a chunk of cash I want a product that has some history behind it.
2.Is my receiver, stereo or amplifier is worth fixing?
The first indication as to whether or not to invest any money in your unit - is it's age. The older the unit,
the more likely it is that you DO want to spend money on it. The second indication is it's weight. If it
requires both hands to pickup, and you risk a hernia lifting it... Its definitely something you want to invest
in. If your receiver has a dial string tuner, you wont easily replace it's sound with what is available today
for less than a grand! If you can pick the unit up with your pinky finger, well, forget it - go buy something
The silver faced units are almost a given that they are worth investing in. Some older black faced units
are also worth your time and money to get them repaired or restored. Just depends on the model. You
can do a quick search on ebay and see what they are going for - be sure to check the 'sold' ones. With
few exceptions, if it's selling 'good used' for around $50 - well, it's definitely time to go shopping for a new
