Question about Amplifiers & Preamps
This unit suddenly stopped sound output to both channels - the twin cassette decks, CD, tuner and turntable all work fine - there is just no output to the speakers - i suspect the power supply unit has failed but have checked both fuses and they are OK.
Is this one of the units that has a ribbon cable ( looks alot like an IDE hard drive cable) that connects all the components together? It also has a squre plastic fan that protrudes slightly from the rear (by about a 16th of an inch)? If so, it's the power module which consists of 2 boards (along the fan housing). You can probably find replacements for about $70, but I wouldn't bother. They quit making new replacements several years ago and any board you get now is just a pull from old stck units.... and they fail about 2 minutes after you put them in. Pioneer knows this but still sells the defective parts.
