Hi all, hope you can help.
I have a PRS MT15 on my bench, and as the title says its making a horrible screeching from the speaker.
Now for the interesting bits,
it does it either in stand by or not, I've checked with a scope.
it doesn't do it with a dummy load plugged in, only with a speaker
If I pull the phase inverter it stops.
the "presence" control alters the sound of the screech.
I'm a bit stuck guys, so any suggestions would be great full received, Bob
