I played with it again, and you're right, the PW only affects the
square. But sine is definitely not putting anything out. I checked
the cable and connections are good. The only thing is, on the
connector board, it's a plug-in connection, but on the other end, the
ribbon is broken up into individual wires, that are soldered to random
points on the board. Is it possible that maybe one of the wires is
soldered to the wrong spot Maybe I could take a picture of that
board and where everything is, and one of your techs could take a look
and make sure the placement is okay If it's a minor issue like that,
I could fix it myself. Otherwise, I talked to Shawn Cleary at
Analogue Haven, and he said the turnaround time for repairs is about
2-3 months. Eek!
