when you say the cathode is connected in the center of the VV it is just a CT DHT filament with the CT labeled cathode... the tube is still directly heated, it just has a cathode tap...or thats how i see it.. the tube drawing shows the filament CT connected to a cathode, but i have yet to see the cathode element in any of the tubes... has anyone else???for it to be an IDT like most people call it it would need a cathode sleeve... i suspect you could ignore the cathode connection altogether and wire it with a traditional hum-balance or DC and the tube would function the same... but given that the CT is there you would be foolish not to use it!
