Hello everyone, I lost my Theremini’s power supply when I moved and it looks like it’s impossible to buy a new original moog one. I tried to buy something online but it doesn’t work properly - impossible to hold a clear note, it’s noisy. It’s a plug directly connected from the wall to the device instead of the 2 part power supply with a box in the middle. Is there a way to replace the power supply with something better? Thanks
