Help Please! 38-116 Troubles
#1

I have 38-116 that I hae recapped, rebuilt all the bakelite caps, checked and replaced most of the resisitors on the B+ side, and checked all tubes. The radio humms faintly and I have approximately 30% less voltage across the board on all pins, of the higher voltage tubes such as 6l6's, 6j5 driver, 6r71st audio etc. If I pull one of the 6l6's I then get 80-85% of the volyage back, I get static theru the speaker which I can adjust tone and volume. I did not worry about an actual audio signal yet. Would it be safe to say I have a bad/weak transformer? If not any suggestions on where a short may be that I am missing? Plate ac voltage at pins 3and 5 of the 5x4 are 381 and 385v.

New input transformr and speaker coil/ output transformer check good along witht he 75 ohm and 400 ohm chokes.
Bob
