Yamaha 2 speed Rotary Speaker unit

Описание к видео Yamaha 2 speed Rotary Speaker unit

This rotary speaker unit and the extra speaker came out of a mid 80's Yamaha spinet organ.
New for 2021-I have found the schematic I made for this way back when. I have changed computers several times since then. If you comment with an e-mail address I will send it to you. Be aware, that there may be some discrepancies between my drawing and what the original schematic says. All the information is in the comments. Use at your own risk.
