Had an Etherwave for a couple of weeks and have noticed that, even with the volume knob adjusted correctly, there is a slight audible tone from the theremin even when the volume antenna is being held. Can I stop this from happening by fiddling with the oscillators?
Anybody able to help me with this?
Hello, You may want to adjust L11 lug which is the left most of the 3, and you may want to check L5, and L6. It’s possible that in shipping, the lugs became unstabalized. Just give them a light tap to make them sit better. You may want to consider drilling access holes in the top of your cabinet to make tuning easier. If you try to do it with the lid off, you will get a lower pitch, or different volume charactoristics when you put the lid back on.
If this does not work, contact Moog for an RMA as it’s covered for a year.
Mine was one of a small batch that went out with a bad power supply, and they were very swift about getting mine back to me.
Hope this helps,
