RE: do you have enough tubes to make sure one is complete?
Posted by Lew on June 14, 2012 at 08:35:06:
For a circlotron output stage, output impedance, Zo = Rp/(2+mu), where Rp is the parallel sum of the plate resistances of the tubes on one phase of the output stage. So you can see that the more tubes in parallel, the lower will be Rp and the lower will be Z.
