Hello to all

My CS 80 Sub Oscillator works fine with aftertouch but not direct.
And one of the preset selector lamps stopped working (bass) what
kind of replacement should i look for ?
There's someone in the group who researched this and found a replacement and I think sells them. Sorry - forgot the name right now but you can search old messages for bulb.


The other problem i have: my CS 60 is just the opposite the Sub Oscillator works fine direct but not with aftertouch. any clues on these matters ?
I traced this out and posted a picture that shows the schematic and board layout for the sub output here:

It looks very simple. There are 2 white wires coming off the sub board from the sub output. One goes to the TRG5 board for the sub aftertouch and the other goes straight up to the direct knobs on the front panel. Looks like a bad connection or broken wire - at least for the CS80 problem. Should be very easy to spot and fix.



Is there maybe somebody over here who has the complete and correct dimensions for the CS 80 stand ?
I can do this in the next couple of days.
