Thanks to all that helped me with this problem I was able to fix it.The problem
was the 2 resistors (RZ123 and RZ124 both 3.9 ohms-2w) and pico fuse FD102s
(3.5A) and of corse the 2 STK-392-040.Did conv.adjustment and out of the
door.All components are located on Power Amp.Board.
Thanks again and specially to William Rayburn who sent me the schematic.
Jorge.

Also look for pico fuses hidng under the cooling fins. There are some of
these that have picos that dont even show up in the schematic.
