I have now found that the metal front trim plate has to be gently prised off - it's held by 3 screws underneath, thee clips at the top, plus some double sided tape sticking it to the plastic panel . The latter is fixed to the amp. chassis with two screws, plus the securing nuts on 3 pots and the function switch!! I was then able to dismantle the function PCBs, seperate the two, apply servisol to the rotary switch, and two inter-board sockets. When reassembled the function switch worked perfectly, or it did up to when I switched theamp. off at about 5.50PM
