Nathan's 37-690X
#40

Yes, I'm still working on this beast. I've been regluing things on the cabinet and derusting yet more parts.

Today I fixed a few remaining issues and got to the alignment.

It took me a while to get the tuning mechanism back in the right order - and had to review the Philco Automatic Tuning service bulletin as well as the (inadequate) photos I had taken earlier when I disassembled everything. For the record here are the steps:

Step 0
