I'm still stuck on this one. I just cant get the D**n thing to respond to a signal further away then a foot from the secondary coil.


There are three coils that you adjust to set the frequency for the remote you are using. The set I am working on is a Control 5 set which is 355khz. Two of the three coils respond (make a difference) when you adjust them. The one that doesn't seem to make any difference is #74 on the schematic. It is one coil that controls the grid on the 2A4G Thyratron tube. The coil ohms out fine, and I have changed the mica cap out, the wiring has also been replaced for all the coils in the radio.

I have double, triple, even quadruple checked the wiring and I cant find anything wrong. I even have another untouched un-restored 39-55 chassis here to compare things to. All of the caps and resistors have been replaced in the radio. Voltages on all the tubes in the MC section test out fine as do the tubes.

I even tried the antenna from the 39-55 on my 39-116 and it works fine with a remote out to about 6 feet which is as far as I have tried it.


Any and all help is welcome. Few more hours on this thing and I think ill have to give up.
