Finally!

Last night before bedtime, I went back to the bench just long enough to see if the chassis was receiving on all three bands. It was - but boy, was that band switch ever dirty! And I hit the wafer sections with DeoxIT while I had the RF unit apart. Strange.
So...
Today, I sprayed the switch wafers again - this time, with contact cleaner - then I had to go out for awhile.
By the time I returned this evening, I felt the contact cleaner had had plenty of time to evaporate, so I tried it again and it was just fine.
I reinstalled the volume control shaft, gave the chassis a complete alignment, and now it has been moved into its new home - the 38-624T cabinet I refinished a couple months ago.
So...how well does a 37-640 chassis fit inside this cabinet?

Not too bad. The 5Y4GA has a fair amount of space between it and the top of the cabinet. I won't ever be playing this radio for hours on end anyway, so it should be fine.
I did have some trouble with clamping the shadowmeter in place. The clips and the frame behind the dial scale were interfering with one another. But I finally managed to get the shadowmeter clipped into place.
Yes, the shadow is off center. I'll address that issue later.
So that is it for this 37-640 chassis restoration. I've fallen way behind on answering emails, and I also have a number of thank-you notes to send out. My apologies. I just really wanted to get this finished. I'll spend the next 2-3 days catching up on things...so if you've sent me an email or if I owe you a thank-you note, be assured I am not ignoring you.
Now stay tuned for the next project - installing new power supply electrolytic capacitors (and new silicon rectifier diodes) in a Sherwood S-7900A receiver.
