I'm hoping to reproduce a speed control circuit. It powers a 110v AC universal vacuum cleaner motor which is installed in an old-time payer piano. The electric suction motor overcomes leaks in the old foot-pump player piano. It's designed to provide two, pre-set motor speeds; a high-speed for playing, and a low speed for rewinding the piano roll (when less suction is needed). The switch-over is controlled by a micro switch attached to the piano's rewind control. The circuit has 2 potentiometers ("play" and "rewind"). Not being an electronics tech, could anyone help me?
Here's what I can read on the components:
3-Prong connector (between the 2 potentiometers): BTA12 800BW, GK2AC VU, CHN 549
Toggle Switch: 8A 125V AC
Red capacotots (?): DME-F250V, CO-104K
The 3 wires on the right side are labeled "NC" "NO" "C" (Normally Closed, Normally Open, Common?)
Many Thanks!
Phil
