Philco 84
#32

The 460KC IF comes thru nicely with the signal generator set to the lowest output and being fed thru a .01MFD cap to the antenna connector. The IF condensors #11 and #15 tune it just fine. But no matter what frequency I place the generator on or output level I cannot hear any signal thru the speaker, not even the faintest noise.

Maybe I'm not checking the correct point on the 77 tube for oscillator operation. From what pin to what point do I need to connect the meter to?
