I forgot the second stage of williamson was the split-load inverter!
What was I thinking???Anyhow, keep the driver circuit unchanged (don't delete the first
stage) except for the before mentioned elimination of the feedback
line connection, and the addition of a 470uf cap to the first stage
cathode resistor *Which you will now have to recalculate for a
single resistor OR simply parallel a 1.2K with a 470 Ohm and this
would be your cathode resistor. (Sorry, too lazy to calculate at
the moment for single R!)-T.M.
