Thanks for accepting me. The problem with my amplifier is with one of the voltage selector switches on the rear panel. There are two switches, one sliding switch which is ok and the other is a round switch which it turned so the pointer lines up with the selected voltage. The round switch has the front part missing, this is the part which connects with the 6 contacts inside to join various primary windings on the main transformer. If I knew which contacts were made for 240V I could join these wires inside and it should be ok. I don't have a wiring diagram and the 6 wires go to either the transformer or the main pcb. I thought about using a multimeter to see what voltages are present but without knowing which wire does what, I'm struggling. If there's anyone who is familiar with the SA range of Pioneer amplifiers maybe they are familiar with this problem. I'm sure I'm not the first person to find that the switch has the front missing and I've tried to find a replacement switch with no luck. I figured the simplest solution would be to join the wires in the same way that would happen with the switch in the 240v position. Any help would be appreciated. Thanks.
