Very little PITCH variance, Etherwave.

My Etherwave only has a playable area range of about 8 to 20 inches, and this range is achieved through only about a 1/10th turn of the pitch potentiometer. A turn of any more than that to the left or the right bring a ambient wine that no amount of backing away from the pitch antenna will quiet. Before I de-solder the weld I am hoping someone might point me to some other possible causes. Thank you!
This is a build your own.

A little background: and I have just gotten my first etherwave as a birthday gift from my wife. It is the solder yourself model, and after three weeks of finishing the case, of which the top is still only at the point of being sanded and treated with a prestain evening agent. The bottom has been sanded, treated, stained, and sealed. I made sure the material used to finish the case are non-metallic. If it seems like three+ weeks is a bit much, A week of that was daily sanding of about an hour per session starting with a 180 grit and ending the last few days with 600. The unit is smooth as wooden velvet. The second week consited of working with different stains and stain combinations on non-showing areas. I only finished the bottom of the case because I could not wait to play anymore. I am a reasonable hand with a soldering iron as I play around a bit with circuit bending. I have minor theoretical background in electronic and enjoy the found noise aspect of what I do. I have six feet from my theremin to the next computer or synth, and I have these off while playing. I have been a window (err linux actually) enthusiast looking into the glamorous world of theremin artist for years. The women, the intrigue, the poppies (poppies poppies poppies), fast cars, corner offices, swiss banks accounts....I can't wait to enter this world, any help or thoughts will be warmly received.

If I am using in terms inappropriately, please let me know.

Does no one have an Etherwave that can let me know if this is normal or not at least? Have I just been too obscure in my description of the issue?

Hi, Birdsong--

No, that's definitely not normal.

My Etherwave Standard (also assembled from a kit) experienced a drastic shrinkage in playable area when it was about three months old. Fixing the problem required adjusting the internal lugs L5 and L6, using the red plastic "trimmer tool" included with the kit.

Alas, beyond this information, I can't help you. Good luck!

The exact procedure for adjusting the Etherwave oscillators can be found here (http://www.moogmusic.com/manuals/HotRodEtherwav.pdf).

Brian and Thierry:
Thank you both very much! I was becoming disheartened..... playing with such a shallow variance field from square one make an already steep learning curve near disastrous.

Brian,
Sprechen Sie oder verstehen Deutsch? Große Übersetzung von meinem Namen. Well alias anyhow, thank you both again, I am at work but can not wait to get home and give this a shot. I will post on progress, cheers!

VL: Ich verstehe ein Bisschen, aber ich spreche nicht so gut, immer mit kaum Grammatik (Q.E.D.). :-/


Seriously, though, glad to help.
