Crist looks like the control is showing only two connections when you switch it. 1st pos. the .006 cap is in circuit. 2nd pos. no connection and 3rd pos. .008 and .03 cap in circuit. Maybe someone can explain further about why its noisy in pos 3.

Oh that sucks. It’s something easily overlooked. Hopefully it’s nothing more than a resistor! Ron462ron — 08:08 AM
