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.

Re: 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.

These items are not known as repairable units. The cost to work on the unit may be more than the cost of a new one.You are better off buying a regular separate type system as these get you into this kind of trouble when they go bad. Dual cassettes even on stand alone unit are no better- abandon the dual cassette type unit they are nothing but trouble and they do not work very well when they are running- I base this on more than 40 years of repair experience.
And yes, I have repaired them but I am not doing it for $8.25/Hr any more.
Hi! This is normally relatively easy. You just connect the tuner output to the line input of the deck. Normally this is done with the amplifier where the tuner go to the tuner and the tape deck to its connections just line out to the cassette input and the cassette line out to the tape input of the amplifier
This would be easier to help you with pictures but I will give you the basics. There should be an input that is labeled either cassette deck or line in. That is where you will plug in the cassette player (that is coming from the output of the player) The cords should be red and white for left and right audio. The back of the tuner should have an output labeled something like preamp out. That will be any number of types of connectors but you should be able to find the right cables. From that output put that in the left/right channel of the amp. It may be labeled something like channel 1 channel 2 input. The speakers will go to the output to the speakers probably also labeled channel 1 and 2. If you post pictures of the backs of all of the equipment I will get more detailed.
Not true! CD channels don't require a pre-amp and the cartridge for a turntable does. I suspect that when the power went off the mixer was still on, so that when power was restored it came back on. However this resulted in a surge inside the unit. Magnetic cartridge pre-amps are often very sensitive to this kind of thing and will sometimes fail, while everything else works fine. This would result in no sound from the record decks, but sound from CD players etc.
your receiver has (or should have) input and output connections,, your turntable needs to be hooked to the receiver,, then with the output cables that feed your cassette player you need to go, in to out and out to in ( receiver output to the input of the tape player, and out of the tape player to the in on the receiver, while playing a record if you hit record on the tape player it will record the record, depending on the receiver it will show you the meter readings for either the in or out,, they vary
