    power switch noise

    Post by j beede on Fri Feb 18, 2011 11:28 pm

    Anyone have any luck reducing power switch turn-off pops or snaps in a Mark2/3/4 or ST-70? My Mark IIIs send a nasty "snap" when I power them down. What works?

    Try placing a .02 uF capacitor @ 200 volts or higher across the switch terminals. Usually that will stop the noise.
