The Fisher 4400 FM Receiver
#7

As Brenda mentioned I'd check those diodes, the Fischer GET50825-1 translates to a 1N2326, and those old germanium diodes didn't always age very well. Plus you know every electrolytic left in there is suspect by this point in time along with the resistors, especially any that are passing very much current.

The advantage of working on a stereo with one good channel is the ability to compare measurements between the two.

I know you don't want to hear this, but keep the thought in the back of your mind that the output xsitors you subbed in might have different characteristics than the originals, and matching on these is often fairly critical.

I've checked a ton xsitors with a meter over the years, but don't recall testing any germaniums, except for the 1N34 diodes in my little rocket crystal sets. Anyway, the testers are quick, cheap, and an easier way to match up gain. Good luck, that's a nice looking receiver.
