Hi

My experance with 4-400 in the 50's was a lot of light , heat and
paresitic oscillation, mad neighbors 

AND POW POWER OUT , abt 300 watts ..

Suggest if to build a 6 neter amp is use a 3CX800 that will do 750 watts
a tube , only need 2200 volts on the plate , 20 watts drive per tube ..

that depends on the input circuit ..
