This QUAD audio control unit was manufactured around 1982 and is an example of highly sophisticated audio electronics of that time but now only works on one channel. At the outset, my goal was to replace the 20 electrolytic capacitors in hopes of correcting the problem with unit. But soon after starting the replacements, I decided instead to hunt the real trouble down rather than roll the dice on shotgunning all the capacitors. That proved to be a good choice.
