Not certain of details of the transmitter responsible for the "Growler" on 73.3kHz but if it's a) High powered b) Valved c) Old then it may well not have any! it not being unknown for them to rely on inductive smoothing (plus "stray" capacity to ground) for the reduction in ripple on HT (11kV+) Are there any seasoned engineers out there who can confirm or comment on this?
