Hi,
thx crazeydoc. I did put c1 back but it didnt change the noise. I didnt change the fet yet, the one in there is marked K30A Y 9B. I will try to hunt down a replacement and swap it out.
PP, thx for the reply. The transformer is oblong so I think the only possibility is its in backwards so it would be stepping up towards the output not down.
Would this add noise? Could it be tried the other way withoput blowing anything.
As for the electrolytic caps, they have all been swapped out for polypropylene.
Thx for the replies.
