Hey all, I have recently done a board for the mountain king megalith. Iv just got around to knocking one up and have noted quite a high pitched whine/oscillation. The only time it is not present is when the Output is full up.
My initial thoughts was the gain on the transistors was too high ! Swapped them out for lower gain and still present. Faulty Output pot ! No ! Revisited the board layout and schematic - all is good there. All other basic check ls complete.
Has anyone experienced this or thoughts ?
