The Kawai & Teisco Analog Synths Group

The machine switches off completely - all lights go out and it has to be
switched off and on again before the lights go back on

reasons as you have said. power source?? if its just tunring compleatly
off.as for noise on the off.mine has a slight noise but its suttle and
recordable.The only strange thing i have experenced using it alot is
when I swich patterns and tracks way to fast then I should while jaming
to fast from a master soucrce  the sx240 slaved with give a glich.but i
think that is due to it being on ommni and not all the patterns i go
therw are muted as there saved.Was the nicad every replaced to your
knowlage?How close did you inspect  the traces and ics ? The nicad
damage can be suttle to extreme when it starts to outgas.
