Thanks, Jim and Tom, I have rebuilt the bias supply with new caps, 100 ufd @50 vdc, and heater supply was also rebuilt using 1000 ufd caps, all new. One thing I also did was to install two CL-80s, one in each primary leg, to slow down the current inrush as I upgraded the caps in the B+ to 560 ufd and 100 ufd (thanks, Jim), I read that should be done to prevent transformer clanging. It may be that two CL-80 is too much and is dropping the primary voltage too low. It may also be that one of the 12AX7 tubes is shorted and causing the severe drop in the heater voltage, that will be my first area of attack, thanks!
