LF: Filter capacitors

[howett@mail.globalnet.co.uk]

Hi all,

I note the comments on faulty filter capacitors with interest. 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?
