Rockwell International has always been one the top notch companies. I forget what they supplied the military with for radars or gun fire control systems. It was synchros and servers or gyros or something.
I got lost in that presentation but basically what they are doing is eliminating armatures ans brushes in generators, (they produce noise) and of course the carbon brushes wear out.

I am curious what that technology would do with wind generators.

Out of curiousity I was googling trying to find out.. I found this site It is totally analogue ans is full of multiplying levers and cams For years it was the most accurate gun fire control computer ever made. I never worked one because right after that school I got transferred into missle systems.

I did go to school at WSMR and worked on a missle guidance computer that was analogue and full of 30 volt motors and 10 turn pots.

I'm surprised Eniac used 6L6's.   Didn't those come later following 7027's  ?

The 6L6 was first developed in 1936, it to was a military valve {tube}, as was the E-7027. I hear that after many years, the E7027 is again being made. The musical instrument amplifier companies have almost always used 6L6's, along with the EL34's. If i'm not mistaken the civilian equivalent to the E7027 was the 6550.  I know in all my Fender guitar amps they have always used the 6L6, my Twin Reverb, Super Reverb, Vibrolux. My Ampeg amps used EL34's. Completely different sounds, but i love them both. Carvin makes a rack mount power amp, where you can change the bias, and switch different power tubes for different gigs. All great tubes are made in Europe. I play mostly pedal steel guitar. And for pedal steel solid state amps are prefered. Crystal clean sound with as little distortion as possible. I use the Peavey Nashville 112, and also the Fender Steel King. Both just fantastic amps. But i have used my little 65 Fender black  face Fender Deluxe  for steel. Here's a picture of me and my old 1965 Fender Deluxe Reverb amp, and peavey 2 12 Black Widow bottom. Just CLICK on the picture to make it bigger

Yeah,  but Ampeg for some reason switched to the 7027 on some of their amps.  Had to do a conversion.  The output tubes in the Portaflex and V series amps switched to 7027 but I think the Svetlana  6l66's were interchangeable ?  Don't recall.
