Hi I have a Soundstream ref200 blowing external fuse.
So far I've
replaced power supply fets
Replaced rectifiers
all outputs tested good
Still pulls too much current when remote applied?
Any help appreciated, thanks

Try twisting the transformer to see if the current draw drops. Do this through a limiter, if you have one.
What FETs did you use in the PS?

I already tried it Perry, the transformer is fine, I noticed the large resistors on R channel had warmed up a little so I lifted them off the board and its powering up stable again?
R223 and R222 are causing the current draw when they're momentarily reconnected, could it be a bad driver board?
Did you check the outputs individually (emitter resistors have to be lifted)?
Are all 4 of the emitter resistors with tolerance?
