Good day!

I need your help! In this scheme, instead of tube el 34 want to use kt 88. The driver put the tube 12ax7.

I want to build a stereo amplifier in one chassis.

The power transformer Hommound 378CX Power, 400-0-400 V, 465 mA
The output transformers Hammond 1650P - 2 pcs.

Power supply circuit remade. Check please correct or not?

What changes should I make to the scheme to use these bulbs and transformers? how recalculate cathode resistor for tube 12ax7???

Sorry for my english....
