37-116 Restoration
#33

Well I powered it up for the first time. It "worked" = no smoke/fire and some stations on BC and SW bands. One small thing is that I had the center tap of the power transformer connected to only one of the two first stage 8uF filter caps, so no B+. I fixed it, but for some reason the negative terminals of those caps were connected to each other, but indirectly - not a wire between them. I was wrong...

I'm pretty all of the alignment adjustments are shot since I cleaned the rust from all of the trimmers and there are A LOT of trimmers.

I did make new bases for the 8uF filter caps. The ones installed were replacements with wires, not the stud thing the original ones had. They look pretty OK, but the paint is too "glittery". However it does stick to the urethane.

   

I did replace all of the out of tolerance resistors and restuff all of the paper and Bakelite capacitors. I also replaced "crunchy" wires.

    part

Kind of looks like it did when I started. I guess that's a good thing. It's too bad the wire color fades so badly with age.  I left the tags I used to mark the wires on them. That way I have a little to work with if a bug turns up. It's hard to see, but there is a safety pin used to snug the IF tuning shaft. I need to remember to replace it with a c ring or whatever they're called. The pin's kind of tacky - no pun intended.

Tomorrow I'll probably start alignment. I'll see if that turns up any more bugs.

Someday I need to repair the light sockets. The rubber or whatever it was bases have disintegrated in several of them.

Can't think of anything witty.
