Hello,
I've been enjoying a 1974 2240 for over a year now. It was handed down from a close friend. The condition of this unit was pristine inside and out. I few months back I replaced all the fuse lights with leds. Turned out amazing. The only thing that I could not seem to figure out was the stereo light not coming on during "good" fm reception. Everything else was silky smooth. After doing a little research, I found this to be not uncommon. Wasn't a big deal anyways. Just the other night I was listening to some lps and out of nowhere I lost audio going to phono? I immediately starting to investigate when I lost power to the unit completely. Shortly there afterwards I smelt the dreaded scent of electrical doom. Dammit!!! Anyways, after opening her up I've narrowed the stench down to the the power board. P800. Nothing stands out as being fried, but I'm sure its coming from this power board. I don't understand what caused the whole unit to power down though? The main fuse on the back of the unit checks out. I expected to find more internal fuses possibly on the power board, but nope? Could a bad cap or resistor on P800 cause this without blowing the main fuse? I ordered and received all new caps for P800. Im no pro. Im would like to say this is an easy fix without sending this unit to a repair shop. Im 300 miles away from someone that would look at it. I downloaded the service manual. Any tips would be grateful. Ty so much in advance.
