Technics SU-X302 Problems

SOURCE: PIONEER DC-Z92 CASSETTE DECK AMPLIFIER

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.

check that power amplifier rating(how many watt)must be more than total speaker rating by 20% at least..
exampel:if speakers watts are 100 watt-amplifier watt must be 120 watt.

If I understand your posting correctly, the amp works using the Aux In connectors but not using the VCR1 even when VCR1 is selected correct? If that is the case, there is an internal electronic switching IC (TA9263 I think) that may be defective. This is not a complex repair and can be confirmed easily by any shop that does audio repair. They will trace the incoming signal with an oscilloscope to the IC and see nothing come out when VCR1 is selected. The IC costs less than $10.
