I don't know how to describe it exactly...a buzz out of the woofer, mid and tweeter are higher pitch, but it is also saw-tooth sounding, so I guess hiss would be the wrong way to describe it.
One of the first things I tried was a cheater plug. did nothing.
They are new KT150 tubes, don't have a second pair of 12AT7's to try.
How do you isolate signal ground from chassis ground, and still have them both grounded?
Jolida 3502rc, can't seem to find the schematic
