Question for Big Poppa about Game Changer

new band name: Mos-Fet and the Anodes

Nature will not abide. It isn't just the transformers. The anode, cathode and heater have to have a certain amount of physical separation to handle a desired current capability or things go ker-zap. As for cooler, without heaters, tubes don't work so well. Them electrons need a little encouraging to jump from the cathode to the anode. Shy little bastards.

Silicon does wonders where vacuum cannot (and vice-versa). I've found mosfet based designs to have similar sonic characteristics to tube based amps. Most early circuit designers treated them like vacuum tubes.

Trying to remember my physics. There are only a few ways to make electricity. Thermionic transmission - tubes. Piezoelectric effect - dynamic mics and phono cartridges. Chemical - batteries. Magnetic - moving a magnet through a coil - bass guitars and big electric power stations. I must be missing one - lightning. Just a little physics refresher from your local nuke.
