Oh poor cat. As a cat lover, it is always a lurch when they go. And Sam was still a young cat.

And now what did you do TODAY?
Slight health scare. Went down with the "cold from hell" in October last. And it seemed to come back four or five times over the next 5 months. Feeling wrecked most of the time. Considered Covid, so took a test - negative. Eventually made an appointment, and saw the Trauma nurse at the practice. Put a blood oxygenation clip on, and sounded my chest "It sounds really rattley ". So packed into one morning in mid March, I ended up with a course of kick ass antibiotics, a full spectrum blood test, and a chest X-ray. Saw the Trauma nurse again yesterday. Antibiotics worked wonders, so the problem must have been an opportunistic bacteria had moved in. Blood test was all nominal (who knew there were 5 different kinds of white blood cell; not me), and chest X-ray was completely clear. So finally after 5 months of recurring misery, I'm finally firing on all cylinders again! Back in the gym, leading 14 mile walks, and running. Happy days!

That is Hannah Fry, PhD in Maths and does a great deal on the public understanding of maths and science (we do lots of different Math in our country🤓). https://en.wikipedia.org/wiki/Hannah_Fry

The Audio Research 610T, which is what they are, 800W each idling power. So 1.6kW of heat going into the room. Made from 2005 to ? Now replaced by the not dissimilar 750SEL monoblocks. A bit like Rolls Royce - if you need to know the price, you can't afford one. But if you need to know, a hair under $100k a pair

Classic special effects movie, with an impossibly young looking Leslie Nielsen. Loosely based on Shakespeare's play The Tempest.

I had a pair of ESP6's in the late 70's. Glorious sound, heavy (because of the transformer and voltage multiplier in each cup) and sweaty because of the fluid filled cups. And needs to be connected to the loudspeaker output of a power amp. I could just about survive a side of a record, and then a break to let my head recover.

Megatron Electrostatic Headphone Amplifier
That is an impressive device! And cheap as chips at UKP 0.38 (although it is very similar in USD or Euro now) from Mouser in one off.

Or even the DXTP560BP5 . PNP, 500V, 150mA and 2.8W Surface mount of course....

Megatron Electrostatic Headphone Amplifier
Any thoughts on the PZTA96ST1G ? Surface mount SOT223, PNP, 450V and 500mA. Downside is 1.5W power dissipation. At least the darned thing is still available

KSA1156 is of course obsolete, alas. OnSemi seem hell bent on obsoleting anything remotely useful from the inventory of companies they acquired. If it does not go in a mobile phone, flat screen TV, PC or car or anything with huge volume, they lose interest real fast. Any that are on eBay are >90% fakes

The bizarre thing with the Sanyo datasheet in the subject line says NPN, but the actual data is all negative going - which would only be the case for a pnp. Of course all the AI data scrapers only consider the (incorrect) Sanyo tag line of NPN - and that forms the basis for every human on the web to propagate that nonsense. Or the other way round - it matters not. As Kevin says - the 2sa1968 is a pnp

Eating humble pie. The original diagram was correct. I had to draw up the truth tables to convince myself! Clearly very rusty now with Boolean logic. I used to be a dab hand.

The two captions on the bottom right are the wrong way round. The NOR gate in the bottom middle would do not(South or Africa) and the bottom right, a NAND gate would do not(South and Africa).

RIP someone or another
RIP Tony Slattery. Who is that? Well back in '79 or thereabouts we went to see the Cambridge Footlights, a showcase for comedy and acting from Cambridge University Undergrads. Traditionally participants have gone on to greatness. Been running since 1886 https://en.wikipedia.org/wiki/Footlights . The one we saw - in Southampton - had Stephen Fry, Hugh Laurie and Emma Thompson in it. Aged 20 or 21 at that point. Each of them went on to greatness. This is them back then. Slattery is the guy in the pale sweater. After footlights he had a burst of fame in a satirical review show on the TV - and then nothing. Totally off the radar. Unrecognizable now, he was making a slow come back. He'd spent the intervening 40 years in dependency and mental illness. No sooner was he getting modestly confident in front of an audience, that he had a heart attack and died, aged 65.
