38-4 restoration need advice/ help
#9

Been busy lately, All new resistors and caps. I aligned it, tuning and reception is good on both bands, but I need some help, the volume is low, and it seems like there is too much bass.
I also have some high voltages. These problems were present before, I figured the off spec. components were to blame.
the DC tube socket voltages are around 20-30 volts high, at 115vac input.
heater voltages are ok. Any recommendations?
