Mystery Control receiver
#9

Sorry guys. If I dont end up robbing any parts from the 39-55 chassis Ron is sending me Ill post it up in the for sale section. I do know ill be taking the dial glass for sure and any parts I may need to fix my 39-55 if needed.

Back to the original topic..

I checked voltages and they all are correct or close enough. I did notice that the 2A4G tube started staying "ON" all the time no matter what I did. I even disconnected the Grid and Plate wires on the socket and when I powered the set the 2A4G tube was still "ON". So I swapped it for the 2A4G tube in my 39-116 and now the tube stays off but I cant get it to fire with my signal gen, or the MC remote (tried rotating the freq. adjustment on the remote).

The only way I have been able to get the tube to fire is by touching the ground of my signal gen to the ground of my freq. counter without the positives connected. This must create a bunch of RF noise which the MC control amp picks up and fires the 2A4G.

My best guess now is the MC receiver is so far out of wack that it's "listening" way out of the 355-400khz range. Someone was in this set before me so God only knows how much the control amp coils have been messed with.
