And these vehicles released into the wild in Austin are their R&D project to fine-tune things, for corporate overlords whose wet dreams are of a dystopian future in which they monitor and sometimes prescribe the movements of all 'average' citizens. FTFY.

Feel free to tell me that I'm wildly exaggerating, so long as you provide a convincing argument. I'd really like to be wrong, but I think that level of control is where the world is heading.

Thanks. I seem to recall some spectrum analyzer plots that suggested that ultrafast and Schottky diodes made it easier to suppress the RF created when the diode switches. It always seemed counterintuitive to me.

Now I understand why you called a B+ of 750V "conservative". 845 is a brute of a tube, and I'd love to hear an amp using one.

Cool! I have some questions - no expectation of answers of course, 'cause we all have things to do beyond posting on Slashdot.

What output tube did you use in the SET amp? Did you use ultrafast diodes in the HV bridge? In your current amp, are the output tubes EL84?

Regarding triode-wiring, I've read good things about connecting the screen grid to the plate using a Zener and cap instead of just a resistor.

Love the toroidal output transformer idea, but I imagine it's a bit expen$ive...

Just curious - push-pull or single-ended? Are the outputs triode, triode-wired pentode, pentode, ultralinear, or OTL? Tube or solid-state rectifiers? Stereo or dual-mono?

Not being nosy - just have an interest in the subject, as you can probably tell. If you're interested in the circuit topology angle as well as enjoying the sound of tube amps, you may find this site worthwhile: http://nutshellhifi.com/ My personal favourites are "The Hidden Harmonics behind THD" and "Evolution of THD".

You and I must be of a similar age. I too remember when they were simply called GFIs rather than GFCIs. I came across the acronym before I knew what the 'C' stands for and was confused.

Fun story: I remember a Reader's Digest article from back when GFIs were first introduced. Somebody who was selling or promoting them used his own daughter as a test subject for demonstrations. She was sitting in a bathtub when Dad dropped a plugged-in-and-playing-music radio into the tub with her.

Why did this require legislative approval? If you want to plug something in at your house, who's to say you can't?

Shouldn't it be the other way around? With government stepping in if something is shown to be too dangerous to have at a house, not presumptively saying, "you can't have that until we think about it".

The legislative approach chosen here is for pretty much the same reason that people can't re-wire their homes without approval and inspection: because doing it wrong can endanger the lives and property of other people. In this case, feeding power INTO an outlet may have bad consequences which are not immediately apparent.

YOUR right to rugged individualism and doing whatever the hell you want, ends abruptly at the border of MY right to safety and security. That's a precondition of cooperative, civilized society.

Legislation is needed to enforce that border in cases where people make mistakes or act in ignorance. It's also needed for people who tend to not understand the necessity of such borders. You know - those folks who feel that their selfish pride "Trumps" such trivial considerations as community safety.

It has no way to detect if it is discharging its load through a lamp or an electrician.

I suspect that plugging the panels only into GFCI-equipped outlets would address a large part of this problem. These outlets don't care whether the power is going from breaker panel to outlet or vice versa - they only care whether the currents on Line and Neutral are equal.

Of course, an electrician could get caught across Line and Neutral, in which case the GFCI wouldn't trip. But the best electricians, (or at least the best ones still alive), test for voltage before they put their bodies between Line and Neutral or Line and Ground. And in general, they reflexively avoid touching Line and (Neutral or Ground) at the same time anyway.

It wouldn't surprise me if this practice of feeding power into domestic outlets gave rise to miniature Non-Contact Voltage Sensors; these would clip to a wire, and would light up and squawk if an AC potential suddenly appears.

Google says the app will "surface what matters to you."

Will it "surface" an end to Google raping our privacy and shoving LLMs up everybody's ass? No? Then it's not "surfacing" anything which matters to me.

This seems like the perfect tool for creating perfect tools who live in echo chambers of their own making and think their farts smell like roses.

... a side-radar that detects if a cyclist or vehicle is approaching, and delays the release of the electronic door lock "until the danger passes."

In other words, there is now an even more complex mechanism - with an even higher likelihood of failing - which could trap a passenger in the car, resulting in injury or death. Bravo!
