Re: Coil slowly getting weaker

Original poster: "JT Bowles" <jasotb@xxxxxxxxxxx>
How is this decreasing output voltage? Only way I can imagine, is if conductive crud builds up on the eletrodes of the S.G. ,and effectively brings them closer together ( thus a lower breakdown voltage). 

I shall await further answers, and then check everything that is suggested
thanks for the responses so far

Any more ideas?

I would guess a dirty spark gap first toooo...

Hi, really sounds like its time to clean your spark gap and reset it. that
is why most coils wimp down. cul brian f.
