I was wondering if anyone has tried a DHT as the driver, using separate tubes for the shunt regulator and driver. Not sure how complicated it might be, but it piqued my interest. Would a 26 be an appropriate driver?
I'm in the middle of wiring in a 3a5 for the driver in my Excite. Running at 4ma, 100V just like the 5965, so the C4S remains the same. 4 D cells for filaments to start, series/parallel for 2.8V about 100ma IIRC.
