Maybe I'm dumb, but I don't know what eewiz meant in this context.? Some things that came to my mind are these: To "plumb" might mean to bring something straight to ground.? I'm thinking about a

DC circuits can be modelled as the flow of water along pipes of different diameters and lengths, but modelling AC circuits becomes very complicated and usually not useful. -- This email has been

Not really. Simple DC circuits can use plumbing analogies, as can EMI shielding, but AC circuits require little-known fluid dynamics, so that plumbing analogies are not helpful. -- This email has been

Certainly not. Never heard of it in 50 years of contact with english and american electronic designers. Honest, I fail to understand what it means.

I must say I'd like a translation? pof plumbing in the realm of electronics.

Piqued my curiosity. I'd like love to see this. “Electronics is just plumbing,” is universally idiomatic, no? -- Michael Stokowski LTspice Team Analog Devices Inc.

I spoke too soon.? Still not getting consistent THD results.? The latest zipped files (thd_debug.zip) show that changing .param fft_cycles=67 brought back the 'thd=0.000000% line again even though I

Yes, right!. I need it to arrive 0V on both output +/- Right. the output max is around 30V > > > >

Sorry.? Just uploaded LG_single.asy.? If missing, it could be shorted out in the schematic.? Anyway, I think Andy is correct in that I was asking .FOUR to perform exactly 61 cycles and I suspect

For what its worth they probably won't behave _exactly_ the same in a real design. There's generally a preference for NPN transistors as power elements, meaning that positive side regulators are based

Which country are you in? I know of a British supply of the power transistor at a very low price, comparatively, but not for export.

Hi Ivan, I've uploaded a zip file - some-zener-models.zip - with 2 files in it. The Cordell text file I might have downloaded from here, can't remember. The 1N5241B is in both files. There may be some

OK Tony, thaks for all.

Sorry folks, the example project is here. Sent: Monday, February 03, 2025 at 11:18 PM From: "eewiz via groups.io" <eewiz@...> To: [email protected] Subject: Re: [LTspice] Creating My

Hello all: Ivan, I have uploaded an example project that details how to create a single symbol that permits selection of multiple sub-circuit models. Many thanks to Andy I for his library management

There are actually some "tricks" going on, when a subcircuit (or lower-level schematic) has a "ground" net that comes out on a .subckt pin.? Some years ago I spent some time documenting this, but did

Your upload seems to be missing the LM337 symbol.? And its model too. And it is not a Dual PSU.? Did you upload the wrong thing? IMO, it is dangerous defining a new model for the BZX84B33VLY.?

It looks to me like TLV431AS, making it another member or derivative of the TL431 family.? Connected this way, it would be 1.24 V. I don't quite follow.? The zeners on the output are 33 V (+/- 0.7),

FYI - I made some changes to one of my previous replies, which mostly do not affect this discussion, but I want to be more correct about them. In most common usage, -55 to +100 C would be somewhere
