So a few years back I had to change my PSB sub transformer as I moved from the US to Ireland.
I replaced the transformer with a toroidal one and all was working perfectly for a few years.
A few days ago I have very little output next to zero... When I put the volume up, a rapid noise occurs, and increases rate the higher the volume. The power light also dims.
I have a sound file I'll try to link.
I noticed the transformer is bulging a bit on two sides, all the caps look good.
I'm getting 17.1v from each lead but I didn't check amps yet.
Could this be caused by the transformer?
Not sure if the board uses jfets or what type but I'm not familiar with this symptom really.
