Hi all,
I have a Kurzweil PC-88 keyboard with a dead left channel main output. Both channels work properly via the headphones. Can someone point me in the direction of a schematic? I have a donor keyboard but the outputs board on it has other issues that make swapping the two not practical. I'm hoping I can identify the components that make up the left channel output and just swap them individually.
i service a lot of casio keyboards and the most common thing to go wrong with them is bad headphone sockets - this often causes one or both channels to cut out due to the internal switches in the socket - try swapping over the headphone socket from the good board
Thanks, I'll investigate that. I'm pretty sure the signal does not "pass through" the headphone jack, because as far as I can remember the line outs continue to work with headphones connected... but I'll double check!
