Hello Theremin World. I'll start by thanking you for this community, I did a good amount of reading here before recently buying my first theremin for my wife and myself. It's a used 90's Etherwave kit (Moog, but produced under the Big Briar name). It seems to work very well, except one issue - when the left hand approaches the volume loop, for the last 3-ish inches the volume increases.
The volume loop functions as expected from 3 inches and further, increasing the volume as the hand distance increases. But, it somehow inverts it's behavior at close range. I have read about a 'chirp' or beep that happens on Etherwaves when you touch the volume loop, but I have not been able to find any info about a steady increase of volume happening at close range.
I am happy to tinker but would love some direction, if anyone knows of this issue. Here's a video example of the close-range volume:

Thanks again,
