Low voltage 301 operation using a light bulb: Somewhere on the web there is a nice article on 301 tweaks etc. in which using a light bulb in series to drop the motor voltage from 115 down to the mid eighties is touted. Reported to quieten the background. Softly glowing light bulb would be cool. Low cost. Or . . . got a variac? Worth a try using a rat-shack voltmeter.
Follow Ups:
My oscillator has variable output voltage so I can choose any combination of supply frequency / voltage / brake load I want.What I think sounds best is brake full on, voltage down fairly low (about 100V) and frequency set to give correct speed.
I am hoping to replace the motor soon so it won't be a problem any more.
