In restoring a 39-116 with considerable rewiring. Injected AF a 2nd Detector/1st Audio produces a tone. From there back nothing...checking voltages I find the plate voltage of the IF tube at 260v (In looking at documentation for the 76 tube near its limit it looks like) with a schematic indicating 160v. I did rewire both the IF cans due to bad rubber wire....replaced the resistors in the 2nd IF can.
I'm still learning on this so any help is appreciated here.

Thanks.

Jeff
