This afternoon after putting in my study time, I decided to try again to troubleshoot the multiplex decoder in my 440-T.

It turned out to have multiple issues. Q402 was bad and I replaced it with a used, tested 2N2614 pulled from another, dead multiplex board. Then I wasn't getting any B+ voltage to the collector of Q401. That turned out to be poor solder joints at Z402. I went over the entire board with the soldering iron and solder, touching up every solder joint on the board.

I reconnected the LED Stereo Beacon, following this diagram as I used on my 4400:

Then, I hooked everything up...and it was off to the races. The Stereo Beacon seems a bit dim to me, but it is otherwise working very well; when tuned off station, the LED goes out immediately.

Let's see...that took only a year and 17 days from start to finish...but at least it is done and seems to be working well.

Oh, and no, this is not the same face plate that I started out with. This one is very dull on the edges but all of the lettering is good, as is the Fisher logo.
