The 76, detector stage, won't have the same reaction as in most other radios. It's connected directly to an RF coil so won't cause the usuall audio hum.
This is a superhet radio with an oscillator. It's hard to check in your radio but can be heard in a second one. Tune your Crosley to 1000 and you should hear a tone around 1450 in a second radio. This will show the oscillator is operating. Try reversing 6D6 tubes. Even though testing good one may not operate as an oscillator?
You mention having B+, does this mean on pin #2 of all tubes and #3 on 6D6's?

: Thank you for the schematic for the Crosley Fiver Jr. 5M3. I'm still having a problem getting it to function. So far I have Recapped it and replaced defective resistors. I have B+, and the tubes test good. IF's appear to be good. However, the only sign of life is a hum when I touch the grid on the audio output tube. I cannot get a reaction from the next tube back (76) or from any other stage. Does Riders or any other source have pointers for this one? Do you have any insights? One problem I did have with the schematic you sent a couple of weeks ago is that the capacitor section of the parts list does not match the numbers on the schematic. Thanks for your ongoing support.
