Question about Audio Players & Recorders
SX-950 31year old Pioneer Receiver will sometimes click on with the surge protection switch and sometimes not. If the unit does click on it will play fine for a minute or so then click off again. The power relay part no. ASR-019-0 type 4U 24VDC is the problem I think. Of course no one has the part or will help with cross refrence for a replacement. I have thoroughly cleaned the inside and rewired the speakers.Do you have suggestions or even a solution.
The relay is a protection device for the speakers. It will shut off the speakers when problems are detected internally. I would suspect that some of the capacitors in the front end are in need of replacing. This is a common item for units this old. I have restored a number of these for customers over the years with much success. Figure about $15-$20 in parts for this repair plus the local labor rate. This unit is definately worth a refurb. What happens is that there is dsome DC voltage being leaked into the final amplification stage. This triggers the protection circuit to shut off the speakers. DC voltage on a speaker will heat up the coil and eventually destroy the speaker.

Fortunately this old school has this protection, otherwise you would lose not only the output transistors, also your valuable speakers.
