A whisp of smoke came from this receiver on the weekend and I am nervous to
use it now. It used to take a second and there would be a click, then it
would power up. Now the click is not there, but it still seems to work fine,
but static comes over the speakers on power up. The resistor that smoked is
next to the little plastic switch looking thing on the right side of the
board. Ya think it can be repaired or is it toast-tea-toes...Thanks. I don't
know my way around this stuff at all.

My guess is that the speaker cutout relay circuit died. I believe its
supposed to disable the speakers until the set is ready. Hence, no click and
you get static at startup.

Just my 2 cents as I don't work with audio electronics
 
I agree,
Audio output relay circuit, contacts either welded on, or
timing circuit has bitten the dust

Thank you to the gentlemen that replied, appreciate the input...

Oh, btw, ya figure the old fossil can be repaired at a reasonable cost or is
it ripe for target practice?

I'm not sure how much it can be repaired. If you want to talk to repair
experts, try sci.electronics.repair. They may be able to give you a better
informed opinion.

Repair will depend on someone having the schematics or repair manual, the
availability of parts, etc. However, the kind of problem your receiver has
should be simple to isolate and repair from a technical point of view.

Good luck.
 
Parts expense should be no more than $10 AUD, repair will be around $80 AUD
