Indeed they do. The R66 from 1957 is one of my favourite sets

Re: Nothing In Particular
This is really interesting. I used a lot of gate drivers in my Tesla Coil days, but they were all two-state, on or off, never linear. High Qg in low RDSon high voltage FETs were always a bitch to drive, so I tended to use either Maxim devices or the ubiquitous UCC36321/2 chips. For HV isolation we u...

Re: Eagle is now subscription-based...
Its down to inertia and the cost in time getting used to another toolchain. Completely agree. I still believe that the right technical decision is to go to CircuitMaker, but lack of bandwidth to manage the transition means I just paid the money to Autodesk for 1 year's Standard license - I used to ...

Re: Eagle is now subscription-based...
So you've stuck with Eagle... I'm still 50/50 staying Eagle or going Circuit Studio... CS allows you to import all your Eagle stuff and have access to all of Altium's huge component catalogue.... supposed to be quite intuitive to use, but, hey, anything is intuitive compared to Eagle.... There's a b...

Eagle is now subscription-based...
Not sure how many folk here actually design PCBs, but... ...as all Eagle users will know, Autocad acquired Eagle from Premier Farnell at the start of the year and Eagle 8, the new version, has a completely different licensing model - it's now subscription based, starting at USD 15/pcm for the "...

Re: Nothing In Particular
Our main dog (a German Shorthaired Pointer) used to try to KILL our cats when we first got it. On the point of taking it back to the rescue centre when a friend suggested a "dog whisperer" - a ex-City-of-London Police dog trainer. 3 hours later, the pointer wouldn't even look at a cat - if...

Re: mosfet biasing
I noticed that some of their JFETs appeared in the native libraries of LTspice a while ago... nice devices...Nick wrote: ↑Sat Aug 12, 2017 10:37 pm On a similar subject, I saw this the other day, which is a good thing IMHO,

Re: Nothing In Particular
Maybe but This is what I wrote and I wrote it in 1992 - "Litz cables are two coated (insulated) wires, one positive the other negative, woven together, which ends up having very high capacitance. This creates a virtual short circuit load on the amplifier at very high frequencies". Maybe s...

Re: Nothing In Particular
First part - because you said it didn't effect audio frwequencies, pretty basic and important mistake. No I didn't. Not at all. I said that the effects, which I quantified, were negligible. Please don't try to twist my words to suit your argument. By presenting my reasoning, others can make up the...

Just for my own elucidation, so I can improve and be a better person in future, where was I factually wrong in my post about Litz wire? Just stick to facts, please.

Re: Nothing In Particular
Not sure what I wrote was pathetic. It was, though I say myself, carefully reasoned and factual.
Sticking to bollocks (bleugh!), here is another interesting fact::
The word Avocado comes from the ancient Aztec Nahuatl word for a monorchid - a bloke with one ball.
Makes sense, really.

Re: Nothing In Particular
FWIW, I only remember one instance of the word "bollocks". This raises an intriguing though perhaps futile semantic point. Can you ever have one "bollocks"? You can definitely be a monorchid and have just one "bollock"... but "one bollocks"? No. Surely not. .....
