Hi folks,


Just received a used etherwave plus theremin today and want to check something...


I'm finding that the theremin produces a buzz - which sounds like somewhat aggressive ground loop interference - when my right hand is just before the lowest note in the pitch range. So however I calibrate the pitch, just before I move my hand into the sub-audible range I hear this low, interference style buzzing. Once the instrument is producing audible notes the buzzing goes away completely, it's only when my hand is just about to enter the audio range.


I didn't find the right solution from the Internet.
