Yes I don't like diode droppers. There were more heater failures in Thorn sets with diode dropper than any other set we came across. Initially in the TV22 I'd dispensed with the HT & Boost diode valves and was trying silicon, so the chain was even lower resistance. Wasn't happy with silicon so added a PY33 & PY81.
