Question about Pioneer Audio Players & Recorders
Is it a big job to replace lamps in this unit. Right now the fm stereo lamp is out and the meters are slightly dimmer than the rest of the unit. I would like to get them all replaced. If I was to take it to a tech what migt I expect to pay for this service or could I do it myself. Myself being a maint tech for a cable Co for 27 yrs. Thankyou

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.

Any luck with checking antenna connections? I have a service manual if you need it. Tuner section in this old girl predates the LM7001. Uses ha1137-38 chips, bit more complex to repair.

You might try to get some information from: www.servicemanual.net. Somebody will need it if you want it worked on. If it is real heavy (40lb.s +) it may well be from the 70's. Mostly good units. I wouldn't give you $0.10 for their new stuff.

Check the speaker wire. Sometimes it can just be loose in the terminals and cause distortion. I have had the problem before.
