Hi Guys,

would someone be able to calculate the filament and plate current draw for these 6 valves.? The filaments are wired in series with a 19V Dc supply,  for each set of three valves ( each receiving 6.3V ? ) The B+ should be  260V

Many thanks for your help.

I am trying to figure out the transformers I will need to buy.

Michael

Further conversion & calculation needed to figure the AC transformer from the DC demand.
