High power GU46 SE amplifier - help with certain issues

GU46 again

I'm enbarking in a GU46 SE and I wonder if I'm in my right mind.

will use 1500V for rail voltage and 250mA

Filament will use Rod Coleman regulators.
Still deciding amplifiyng and driving stage.

Wish me luck and I welcome any help
 
This is how it turned out.
GU46 in SE, triode mode 1500V , 200mA (both plate and g2).
It puts out over 80W rms with less than 1,8% THD.
The best mix of grunt, power and delicatessen I've ever experienced.
My daily amp, but more suitable for winter as it draws always 4,8A from the mains.
