I looked at the schematic for the 37-630 from the library here, copied the PDF of the service documents. I compared it to the schematic I printed out for the 37-640, which is also from the library here. From what I can see the two tuning sections are IDENTICAL. Most of the part reference numbers are even the same, as if someone did a copy and paste when they made the 640 schematic, more likely a tracing back in those days. Just to be sure, can anyone else verify this as a fact? Do any of the real experts on these models here either know if they are exactly the same, or are their differences I missed? I have pulled the tuning section from the 37-630 chassis I am stripping for parts already, and from all I can see, I can use it instead of the NASTY one. It is MUCH cleaner underneath, and will be a much easier job to rebuild, with a much better chance of success.

In other news, this tuning section also had a thick felt washer around the tuning shaft, one in MUCH better condition, so I now have an answer to that question, and a good felt washer to use when I reassemble the tuning section.
