Anyone got a schem for this UK installation amp. Local agents are unable to supply information. NOT user manual (just want to repair it, not use it 🙂 ).

A clue to the fault, if any, would probably help you get an answer.
It is similar to MPA120 and MPA60.

Wild crackling accompanied by intermittent high AC draw (understandable as the output looks straight into a big transformer). Hence need circuit of output section.
