[QUOTE="JANNAS, post: 1056978, member: 2211"] It sounds like DC offset to me. Depending on channel, I will start to check D1/2 and D4/5.The zeners D3/6 are also suspect. Thereafter I will start checking the small signal transistors. Ensure that bias is set correctly before you begin with no load and input shorted. [/QUOTE]
