This is an old radio. It's built like a Sherman Tank. I think I have some bad tubes, but my tube tester doesn't test a tube this old. They are #24 tubes. Antique radio supply wants $20 dollars apiece for this tube, they have a 224 that seems identical. I have 4 of these in this radio. I can hear my signal generator coming in on a tuned frequency (signal generator and dial on radio match) with 2 of the tubes removed. That would be 1RF and 2RF removed. My signal generator hooked to a pin on 3RF. My question is, does anyone have some quick check ideas to find the more obvious problems with the tubes, so I don't have to pay 20 dollars apiece to find out if my tubes are bad.
Also, I haven't been able to locate an alignment proceedure on this model...nom
