Default Re: HAC Regen receiver PSU

OOOhh i dont want that !.
Just looked at the circuit diagram and it shows it is in the HT supply , so maybe an audio amplifier as isolation might be better . I have original 2000 ohm bakelite and steel headphones and i think also a pair of very old BBC jobs.
Reading some of the history bumph it says there was an audio amplifier option.
How do these things cope with local electrical QRM ?.
