I have a Monarch SA-30 tube amp that I am trying to rebuild. If I fire it up everything plays but volumne starts dropping quickly and two of the 6BM8 tubes, one in each channel start glowing like light bulbs. If I remove those two tubes the next in the series start glowing.
The tubes used in the amp are two 12ax7's, four 6bm8's and one 6ca4.
I have ordered new caps for it but would still kike to come up with a schematic for it.
If anyone has a idea of where to start looking for the problem at I sure would appreciate the help.
All tubes have checked good on a Sencore TC-142 and the filter capacitors checked weak on a EICO model 950 capacitor checker.
Thanks
