Cathode drive [message #8850]

Illuminati (2nd Degree)

Given the wide variatin in grid circuit requirements between power valves like 211, 845 and 833 it seems possible to build a pre-amp to drive the cathodes. It also looks like cathode Z is near constant, even when the grid is drawing current....

anybody try this yet?
regards,
Douglas
