Some fast remarks. Details tomorrow. Photos of the amp will be helpful.
Do you have the tuner/preamp that was associated with the power amp? If you don't, we have to build something. Notice that no listening level controls, whatsoever, are to be found in the schematic. What's labeled Bal. is a trim pot., not a control.
BTW, a "quick and dirty" solution to the volume control issue is to replace the R107/R207 fixed resistors with 500 Kohm log. taper controls and connect the pot. wipers to the grid circuitry.
