Thank you Brenda and Mortz , (ladies first). Mortz, would removal of the AVC tube upset anything in terms of testing that area? Obviously the set would lack AVC.
Brenda thanks for the explanation on how the detector is working. I see now what your talking about. Sorry but I didn't realize the detector plate was ran at such a low voltage. I was chasing ghosts but that is how one learns. Dang, those two caps and resistor are inside the can. Fun. Well, can off and I can measure the resistor but not the caps. Should I be able to put my scope on the input to the pi network and see an AF signal? I hope the secondary is not open but if it were I wouldn't get a solid modulated IF signal on the grid of the detector. Correct?
Appreciate both your assistance.
