: [AMPS] 813 amp

>???? why would 135 watts be too much for 3x813 gg amp??

The 813 has enough cathode emission (c.230mA each) for a finite amount of 
drive at a given anode supply potential.   More anode V = less drive P.

//  At 3.2kV, my guess is a bit under 400 clean W/bottle.  I would avoid 
AŘ.
