I didn't found thread about this.
Did anybody played with big core OT transformers, in PP, B-class?
For example: core 40-50cm2, Ra-a=12k, Ua=1-1.5kV, Bandwith 20Hz - 20kHz, Pout around 150-350W.
Tube type: 800,808,809,811 or 812A.
Should work the power stage in this kind of configuration well?

The Driver stage must have around 150-270Vpp... but that is another thread...
