I got three 36 tubes yesterday, all used but tested excellent according to the seller. I put each one in, the best I can get is oscillation above ~1180kc. All four local stations at the top come in fine.
With a digital radio, I'm able to receive rf+lo at rf+238kc. It's supposed to run at 260kc, is that enough of a problem? I don't have any alignment tools, other than a transmitter and scope. Is it possible to align it without a function generator or counter? It seems like the oscillator could be corrected with the digital radio and transmitter, and the other stages with a scope.
Like before, a jumper lead connected to pin 2 of the 36 makes it all work fine. Any more suggestions?
Thanks,
Will
