BDM, I just took a very quick look at the schematic for your Philco 650 over at the nostalgiaair site. You mentioned the shadowmeter was removed from the set. The resistance coil of the shadowmeter appears to be a 5K ohm resistor (wirewound type on shadowmeter). If the shadowmeter wires have been cut loose, then you definately need to sub-in a resistor ( guestimate 5 watter power type resistor) would be OK in place of the shadowmeter coil, until you get the orig shadowmeter coil (if still good) re-installed? I have found in the past, that a missing or defective shadowmeter coil assembly usually completely shuts-down a mid late 30s Philco. I havent worked on a 650 in a long time. Perhaps Ron or Chuck can take a look at the schemat also and provide more info. I am currently restoring 2 vintage radios at the same time, a Radiola mod 80 TRF, & a 36 Truetone D-723 for separate customers. Both were *hacked* pretty bad, but I have both getting audio now, so Im headed in the right direction on both restorations. My heads kinda fuzzy reading schemats right now. (hee hee) Jus tryin to help Randal
