[Ernst]

I'm going to start on my first pre-1940 Philco--a 610 Code 121. Any thoughts, precautions, hints, warnings, sympathy?

Nothing special - just the typical replace all capacitors and electrolytics. Re-build any bakelite block caps and metal can caps.

Check all resistors for out of tolerance values (+/-20%) and replace as needed.

Check all RF and OSC coils for continutiy - also IF and AF transformer windings.

Check bandswitch contacts and clean if needed.

Then do your dim-bulb or vaiac tests.
