Default CITRONIC PPX for help

I got a used ppx900 and it looks fine. But sometime one channel outputs inappositely, it seems HF distortion.

I check output DC and bias, seem in gear. I should contrast with both channels but the trouble is not always appears and the unit is too heavy to overturn timely. Is it some caps or magnifying audions become bad condition?

I have got the schematics. If anyone have its service manual, could help me strongly.
Thank in advance.

py@chainzone.com wishfully.
