I'm trying to build a vox "AC15" clone out of an old PA amp (already 2 EL84). I used the AC30 TB preamp wiring (schematic from tube amp book) and left the power stage as it was. Problem: awfull sound overdriven.
The phase splitter has only about 120V on the plates. I don't have a coil in the power supply, so a 1:1 copy is not possible. How do I have to wire the power supply of the phase splitter to get more voltage on the plates?
Thanks in advance for any answers.

Back up and tell us what the voltage is to the plate load resistors of the PI/driver section.
You might just have the cathodes or grids wired wrong.
