OPA860 ("perfect" transistor)
Well I'm a little slower than piglet, and I'm only up to section 2.3.6 in AoE3. (or is it AoE III?) There H&H mention the opa860, which I would have skipped, except I'd just been looking at that "OTA"...

some flyback switchers
I need maybe +750 volts at low current, 15 mA maybe. Here are some attempts to recover some of the leakage inductance energy and keep the transformer affordable. I got some quotes on PCB mountable HV...

El cheapo rotary vane vacuum pump
I see that Harbor Freight now has 75 millitorr vacuum pumps. I think that's good enough to do neon sign work. Or make astronaut ice-cream in your freezer. Or that agar-based aerogel. So, if I buy two...

NFB Rolloff, capacitorless
Suppose I have a very simple little class B amp, just an opamp driving a sm all output pair for a watt or 2, and nfb resistors. Zero output pair bias, lots of crossover distortion. Now... I'm thinking...
