Bob,
How much plate voltage will the stock VKII tank components handle?  I
have a VKII chassis in need of a serious rebuild and have been
considering external MOD and a different final tube/s.  Without the Mod
circuit the available current can run upwards of 400 ma. and solid state
rectifiers put the Plate V around 800V or better without the Mod load.
