I have built 6 pcs. of K8060 and put them in a enclosure for my home theatre equipment. 5 amplifiers works fine, but i have a problem with one.
Bulbtest and bias adjust is ok, everything looks ok but i have -40VDC on speaker output.
Yesterday i replaced all transistors, still got -40VDC. It seems that power supply part is ok and as far as i can see solderings are ok. I havent replaced any diod:s or caps/resistors.
Anyone?
