I am still working on Model 89. I have it working up to IF tube. Using signal generator I can hear signal at signal grid of IF tube but cannot hear signal at begining of 1st IF transformer#18. Could the compensating condenser #19 be the problem and how do I test it. I am using schematic dated July 15, 1934. Cannot hear signal at plate of 36 tube either.
Thanks for your help.
