He is going to be interested in large tubes, I would guess at least 2" in diameter and a least a little taller, not including the pins.



The last picture from his web site is an example of how he uses the tube. The call sign is kf7jyo steve. He has an engraving machine that cuts glass, marble, ceramic, wood etc. I hope this can be helpful or at least interesting, Mike.

I collect the abscure vacuum tubes, but get plenty I could send your buddy. Just the other day found an old radio that used A and B battery's and had a batery eliminator on it. Ask you freind of he is into wanting one.

I've had my ham license for about 10 years and never once used it, just got it to peserve the bandwidth for those that do play.
