Using Theremin near tube equipment::any danger?

theremins are always placed next to solid state and tube amps. otherwise they can't produce any sound.

No worries- tube equipment will be fine with it. Have fun!!

Not a clue but at 0 to 6000 hz it could if you get it too close. If you have shielding around your tubes/gear though you should be safe. Just move it away if there's a problem. I really just wanted to post some songs that supposedly use Therimin or its cousin the Tannerin. The "Good Vibrations" song used a Tannerin.

Track Listing:

"Good Vibrations" - The Beach Boys

Also sounds like Portishead uses one on some of there music but keyboards can make some of the sounds also.

Have fun.

Although I can't prove a direct correlation, I've worked with a musician whose old tube SVT bass head went nuts when we had an artist bring her Theremin onstage at a festival. The unit was fine for the whole festival run, before and after her set, just acted up the one time. I just attributed it to the bass head being within a few feet of the therimin. If it's a problem just move it further, the field shouldn't be too large to be an issue most of the time

I am more concerned of a Theremin field being picked up by tube electronics.

OK. Nice review and explaination on Wikepedia! I personally don't see a problem, but ask more knowledgable folk. While some frequencies may be generated by a vacuum tube in operation, I can't see these affecting the theremin since they would not be grounded to the unit, as the performer would be. This, BTW, looks really interesting!

All right, I'll bite. What's a "theremin"?
