Re: Low HT triode operation - is it OK?
Presumably it's fed from a relatively low impedance source- with that input voltage and the low bias voltage, grid current will feature over part of the cycle.

Re: Low HT triode operation - is it OK?
Hi Chris.
The stated output impedance of the player I’m using it with is 47K. DC blocking capacitors are fitted on the outputs of the player. Cheers. Simon.

Re: Low HT triode operation - is it OK?
They probably mean 'minimum load impedance 47k'. People, including manufacturers, often confuse 'output impedance' with 'load impedance'.
