Add a master volume control to your non-master style amplifier. This modification works well with any vintage style chassis layout, especially with those that utilize panel mounted potentiometers. Install the supplied 1MA Alpha potentiometer into the amplifier's signal chain inline between the preamp and phase inverter. We supply you with enough shielded wire so that the control can be mounted anywhere on the chassis.
