Properly and safely disconnect M boards

2015-02-15 by gearfire01@...

Hello everybody,


Does anybody have a safely procedure about how to disconnect a M board from the whole CS80 system?

I think i have identified a bad IC on one voicecard, but before having available spares to swap, i wish to go on with other repairs, and for this reason i would need to 'unplug' that only voicecard from the system.

Shall i simply disconnect the -15/+15v supply to that board? (Of course respecting the continuity of the subsequent voice card supply).

Thank you for your help and advices.
