[Amps] HEathkit SB-1000 Arcing

[KG8YN]

I thought I would chime in on this one, since I don't think it has been 
mentioned.

I woked on an SP-200 receiver that had static noise that turned out to be an 
arc inside a potted filter choke.  It could not be heard or seen, except 
from the speaker.

So it could be internal to your transformer.  Since it can be heard,  you 
can remove the tranformer and clip lead it in at a distance.  That should 
let you know if your in for a big expence.
