I am back to look at the third stage of this Crosley. If you are following my Thompson H-3 speaker thread you'll know that I think I repaired the speaker but got no sound when I connected to this Crosley Trirdyne.
Mr. Fixr55 suggested putting my headphones (with which I could hear the broadcast but it only use stages 1 & 2 on the Crosley when you plug into the headphone jack) across the speaker connections. I did that and while I heard a slight buzz indicating the headphones were picking up something, there was no sound from the broadcast I was playing on my SSTran transmitter. I fiddled with the 3rd 01A tube and realized that it is not sitting in the socket correctly. After a little manipulation and a small shim to hold the tube in place I saw the filament light up but unfortunately still did not hear the broadcast.
My next step will be to take the chassis back out of the cabinet, clean the contacts on the headphone switch, reflow the solder on the connections of the third stage and take a better look at the socket. Stay tuned....
