Here is another possibility.
What if either the ouput tranny or the speaker voice coil were bad.
Would either of these cause the very faint audio?
I remember Morzh stated once that if the OT was bad there would be no audio at all.
I am getting slight humm, and I can hear faint audio with a few stations along the dial.
Voice coil?
Is there a simple way to check these?
I did try using my ohmmeter on the output lugs coming out of the OT.
All I got is verification that was continuity.
Just thought I better ask you guy's.
Have re-capped, replaced a few resistors, an checked the tubes again.
Did replace that #7 coil as well.
There are a couple caps that were added at some time that are not on the schematic. I just replaced those with new caps. Tried disconnecting thos 2 as well, with no change.
Stumped again
