Thanks Chuck!- I'm actually getting so frustrated with my lack of knowledge at this point, that I am now reading through my father's "RCA Radio and Television Electronics Course for home study" from the 1950's! Looks to be about 20 lesson books, and 20 matching service practices books.(and I have actually discovered I have most of, if not all, the experimenter pieces which came with it! Even the soldering iron is there! ) I haven't gotten to the books on meter use yet- although I do know the rough basics, of course... ;) I didn't know about the "ohms per volt" issue until very recently, and still fuzzy about it... However, at least we know I can ballpark with the equipment I have for this issue.

I did check votages the other day, and they were within reason, but it was not an "organized" check. I will recheck them, and post the results here. I do have few quick questions regarding the 37-650 in particular: On figure 1, it shows the 2nd DET.- AVC. 6J5G, but gives no voltage for term. "P", although there is an arrow. I am assuming this is "Plate" voltage, and should be 250V as the others? Also, there are no voltages to check on the grids? And are there voltages for the 5Y4G to check? Lastly, it appears I check the one electrolytic cap first across the two terminals for 330V, then from pos. to ground for 315V?

I have tested the tubes, and all are in fine shape, hold well under emissions testing. I remember the radio had been working ok, except for the volume issue, but then just blinked out- and hasn't made radio sounds since... Driving me nuts.

I am now an expert at tearing down and reassembling an RF subchassis, so it isn't all bad...

Thanks!
