Front panel noise ON/OFF switch not working anyone?

Post by Newmoog » Wed Apr 13, 2016 4:24 pm

Hi guys,

my front panel noise ON/OFF switch is not working; OSC 1, 2, 3 switches are fine but only way to silence the noise generator is to zero-knob it. Did anyone ever face this issue and what did you do to fix it?

Regards.

Does the LCD reflect the state of the switch when you toggle between on and off?

Yes, the switch mechanics is fine and the display shows the toggle but no effect on sound.

I replaced U61 to fix it, it took ages to find out.
