Hi, 

many thanx for the info...

>the schematic shows it as a 16-pin chip, with 8 pins used.

The pins parallel to the left and the right don't belong to the unit, at
least not in my CZ-1...

Ok, so it was the right decision to connect 8 with 4 and 9 with 13... it
crackles a little when turning on the synth, but I think it's easier then
replacing the chip (what is the right english name for a "electrical
triggered switch", "Relay" ???) and the ouputs are working fine again. My
guess that this little thing is causing problems in many Casio synths after
some years...

I first thought the unit has problems with A/B know, since on the headphone
output it seemed to be not hard left and hard right anymore but now after I
connected it to the mixer again the line outs seem to be ok that's why I
asked for the pinout...

Another thing, there are 3 adjustable resistors on the same board, one is
for the headphone output but I haven't found out what the other two (sitting
close to each other) for. I may have changed their value while trying out
what causes the output to have problems. It would be nice if you look up
their purpose?

Well, the box is ok here, maybe it's because I'm using an ascii only
mailprogramm... I still think it was a bad idea to use HTML in mail programms...

It's reacting shortly after turning on the synth and stays that way... a
friend had the same problem with his FZ-1, but it was harder to find since
it wasn't on the output board. But the FZ relay had only 4 pins...

Ok, thanx again for your help!
