Is Lindsay?s ?SM? a fraud?

     Diodes hmmmm.  I've seen some hockey puck diodes before but I've never seen tubing potted in to cool them before.    I dont see much of a difference between a diode, spark gap, capacitor, tube.  Just different electrolytes.

     

I was referring to the little cylindrical devices with axial leads found on the large dark electrolytics in the large TPU. High grade silicon and some germanium and other types were encased in a metal can. I know of many, used in military equipment had color bands. The band arrangement was not the same as color coding on resistors. You can google diode color coding and see what I mean.

Most I ran into had functions a bit odd - by conventional thought. The most interesting to me were the SRDs or Step Recovery Diodes. These had an intersting feature of dramatically shortening the rise or fall time of a pulse. I believe they still do a better job than even the fastest MOSFETS. Another feature was their use as frequency multipliers.

NO! He was dealing with electrostatic speakers, the voltage was over 5kV.

I thought that maybe I had missed something, as I had never read Steven discussing electrostatic speakers. Giving you the benefit of the doubt, I checked my copies of his writings, and still didn't find any reference. By chance, could you please show me where he said he was building electrostatic speakers???

Those cyclinders on the caps look exactly like the contained ceramic spark gap arresters used on old tvs to protect the high voltage drive transistors that drive the cathode ray tubes from damage when the tube grids flash over, they also came in a clear flavour, if i remeber red bands meant hydrogen was used as the gas but dont quote me on that.

If my poor brain is working correctly i think it was the old Panasonic chassis.

Also did you know Bose used Saturable inductors in their Class D amps

Hallelujah brethren!

At least I hope that is correct  

I don't have my personal laptop where all the info is stored right now.

This is where I took the 'noise' and ionizer tangent. Stochastic resonance is used to improve signal quality on data signals. I've run across claims and patents using noise and HV with a controlling sine wave to improve body in sound, pull 'lower than noise floor' signals out of chaos, UWB (Ultra Wideband) and others.

Then the circuit diagram posted on this site for those same electrostatic speakers. They had a noise generator built in.

My incentive is this (no need to start the old RMF argument): SM rotated a field. He didn't say what field. Everyone assumes it is the magnetic field. My experience says that is impossible - Wiki be damned. The current idea of a RMF is sequential or quadratic pulsing of separate coils in a circle. That doesn't cut it in my book.

So what field can be rotated? The dielectric field.
And I went from there.

I will. It'll be a few days before I get back to that PC. I'm pretty sure it was one, if not the only patent that could be attributed to him. No, I don't think it was in the commo via Mannix.
