The Fisher 4400 FM Receiver
#58

OK, folks, I opened the 4400 back up this evening, and began to replace electrolytics.

How things looked as I began:

The two newer electrolytics you see in this picture are the two I used for testing purposes when I was troubleshooting the receiver.

I just quit for the evening, and as you will see below, I made substantial progress:

As I removed the original West German electrolytics, I noticed they were rated at 70 degrees C.

I should have the electrolytic replacement complete tomorrow. I'm not replacing the electrolytics on the PC boards yet - perhaps later.

Oh, do you notice the capacitor at lower left in both photos, under the power transformer? That is connected from one side of the AC line to ground, and will be replaced with an X/Y safety cap. I happened to have some on hand from my restoration work on vintage Philcos, which I bought to replace the line-to-ground caps in bakelite blocks.
