Very nice set up. And yes, the HS-80 has a coolness factor, whether it helps the sound or not. I did a double-take when I saw your motor with all those green digits. Then I read what you did.
My RY-5500 came with an external 120 V to 100 V step-down power transfomer. I took the opportunity to add internal voltage regulation into the RY-5500 chassis that simultaneously drops the voltage without needing that external transfomer, makes the motor completely immune to line voltage variations and drastically lowers the noise of the voltage applied to the motor. Not as elaborate as your tach feedback loop but it seems to do the trick.
The 5000 is a great platform.Rerurn to Romy the Cat's Site
