Progress report for today:
I pulled the MPX board early this afternoon. And I just had to try the MPX board from the 440-T parts set. ![Icon_crazy Icon_crazy](https://philcoradio.com/phorum/images/smilies/icon_crazy.gif) Big mistake - I lost FM when I fired the unit up again. So I pulled that MPX board, put the two new electrolytics in the original MPX board and replaced the 2N2924 (Q404) with a known good transistor that had come from my 4400, and reinstalled. FM was back. Whew! Still no Stereo Beacon light, but I'll attempt an alignment in the near future. I'll have to either find, or purchase, a hex alignment tool first.
Four more electrolytics and then they will all be replaced.
The 440-T I bought mainly to get the faceplate is in really bad shape; it looks like it was run until it died the death from very bad, leaky electrolytics. I've decided that it will be a parts donor...that is, if anything other than the faceplate from it is any good.

I'd try replacing the bulb first and if that doesn't do it, then change the 35Z5 and see if the problem goes away.NostalgiaRadioTime — 12:28 AM |
