I picked up a 37-675 that was listed on the sell forum for free a few weeks ago. Pete in NJ did a lots of work on the set along replacing all the caps, some micas, and about half of all of the resistors the cabinet is simply beautiful with it's original finish. It plays well but is doa on the SW bands. After doing a bit of troubleshooting there seems to be a problem near the band switch. Osc and mixer are working fine but I'm not getting any signal from the plate of the RF amp. Will work if I hook the ant to the grid of the mixer tube. If I connect the ant to the plate pin of the RF amp though a coupling cap I get no signal. In the broadcast and SW positions volts look good around the RF amp.
The big question is if I remove the RF sub chaiss will that give me good access to the bandswitch wafers? Looking with sub chaiss in place it looks like there's still a lot of parts in the way of the wafer.
Tnx

figure out what all those squiggly meant.

Now I think I've got!
