I've been making progress on my 37-630 this week. I removed the dial (thanks Terry) and then the entire RF sub-chasssis. I restuffed the electrolytic and replaced all of the paper caps and one out of spec resistor. Even though I removed both of the side walls of the sub-chassis, one of those paper caps was a bear to replace. Finally got it though
I took a wire brush attachmenent to my Dremel tool to get at the worst of the rust on the top of the RF chassis. I'll go after what is left with naval jelly soon.
Last night I managed to check continuity on all of the antenna/RF/oscillator coils. No opens;) I applied some Deoxit to the band switch contacts as best I could and worked the switch for 10 minutes or so. Other than the previously mentioned rust removal and later some paint, I think I'm pretty much done with the RF chassis at this point. Wasn't as bad as I had thought it would be.
