I am building a stereo SET KT88 power amplifier with XLR and RCA inputs.
So far sticking with the 6SN7 voltage amplifier/driver setup and cathode bias.
The first step was to manufacture the transformers. The OPT were 2500ohms:8ohms and should give a wide bandwidth at 8 watts.
Here is the result:

I wanted a beefy choke, and settled on a 10Henry 250mA design.
Here you can see all the hardware bolted together:
