Hey guys. I was given a pioneer A-115, but on getting home, it was dead. Missing voltage selector dial...
Does anyone know how I could bypass the voltage selector (ie hardwire 220 v to the transformer) or perhaps have or know where I can get the missing part? I'd love to get it working as a small secondary HiFi.
Back of offending component.
Inside the amp, showing the back of voltage selector
Another angle
Primary side of the tranny.
Primary side from another angle
Front of the amp
Rear of the amp
Further info:
Power comes in and is soldered to the unswitched outlet
A yellow wire goes from the unswitched live to the switch on the front panel
A brown wire comes back to the switched outlet, where it continues to the board, providing live, which jumps to the transformer on a grey wire. In pics this is the pin furtherst from the board.
Neutral is commoned across outlets and connects directly to the transformer on a purple wire on the pin closest to the board.
Where live enters the board it goes through a fuse 800ma onto a green wire, which leads to the selector.
Colours of selectable inputs on the tranny are white (opp green on selector) yellow(one step from green, anti clockwise if looking from the inside) brown (one step clockwise from green) black (one step clockwise from white) and red (one step anti clockwise from white)
I have a feeling connecting live to white may work but don't want to risk anything going bang.
I'd appreciate any help getting this running again! :dop:
