Restoring Philco 37-620
#2

I would go ahead and fire it up without the bulb; everything sounds OK so far. To be safe, keep your hand on the on/off switch just in case of smoke- a normal practice for a first firing-up.

It looks like an error in the meter range setting; it should be the 300v range. There's nothing special about the recommended Philco Model 025 meter other than the increased loading as compared to modern voltmeters. If you are using a modern digital voltmeter you should expect slightly higher voltages than with older meters.

Keep us informed on the progress or lack there of. The 37-620 is a great radio- mine is used several hours a day. Also, getting into the raised RF stage for component replacement is much simpler than it appears.
