And if the tube happens to have an acoustic resonance close to the electrical Fres... you have a potentially very lossy tube. Maybe Terry should add some weights to the ends of his lossy sonotube coil. Plenty of experiments suggest themselves... Measuring the mechanical vibrations in the presence of large E and B fields could be tricky. Transfer the vibrations along a taute fishing line to an acoustic pickup some distance away perhaps. How about in reverse. Have the secondary carry a few amps DC and expose it to ultrasonic sound at Fres. Look for induced EMF superimposed on the DC across the secondary terminals. Amazing how Tesla coiling continues to present endless possibilities for worthwhile investigations. Cheers, -- Paul Nicholson, Manchester, UK. --
