Fate of Class A

[Bob, W7ETA]

I'll bet you can DIY one for yourself and not have to worry about it--if you can figure it out.

But, what do ya expect from the Left Coast anyway?!

Next thing ya know, they will try and mandate what color roof you can have and insist the colors have special reflective components so that houses don't absorb as much heat.

Left Coast? GSY!

Thanks for that link. I notice in my sims, of a cascoded balanced amp, that varying the positive supply voltage dramatically alters the amp's power requirements--it also alters the output wattage curve. I.e., lowering the supply voltage requires that the amp be played at lower volume or else the transistor's "power curve" suffers. By power curve, I'm using Simetrex's jargon. A ragged looking power curve sine-wave results in poor sonics on the test bench.

I'm going to experiment with varying the positive supply voltage.
