Hoopefully the amplifier will continue working OK now, Alan. The fault was due to intermittent contacts in a rotary switch, which appears to be a fairly standard 4pole 3way rotary type with the stop disabled or removed, connected with all 4 poles in parallel, yet providing 7 different positions (Phono, Tuner, Aux, CD, Tape1, Tape2, & MD) Quite how this is achieved I didn't work out, though! Hopefully, treating the switch, plus two plug/socket connections, with Servisol super 10 will prove to be a long-term cure, but at least I now know how to dismantle the amp!!
