Happy birthday Al! Have a great one.

49 shot dead in Mosque shootings in Christchurch New Zealand. One of the shooters, and Australian ultra-right fucker posted live video. The NZ police arrested four of them. There was also a car bomb that was defused successfully. Christchurch. New Zealand. Nowhere on God's green earth is safe. Fuck. RIP the 49

Well OK, he hanged himself then. But he's just as dead anyway.

I've looked at the auctions from the above. Both sellers have been on eBay for a long time (1998 and 2000) and both have 100% positive feedback. Since Tekscopes only opened in 2001 it is likely that these sellers are not list members All of the more "recent" (ie post about 1970!) scopes have a scan expansion mesh, which makes the traces look oddly defocused as compared with older (tubed/valved) scopes. They had no expansion mesh and had pin sharp traces, but much much lower bandwidth of course. I suspect that he had your scope to bits to replace capacitors etc and forgot to tighten some of the screws, which does not confer great confidence.

If was 7000 series I could certainly give advice. But I have no real knowledge of the 2465A, alas.

Today's news is that he apparently hung himself.

There is a wealth of expertise on Tektronix gear on https://groups.io/g/TekScopes . Join it - you'll like it. Extremely helpful mailing list. You'll get plenty of information regarding triggering performance of a 2465A, and whether it is behaving itself. It is not at all like Head Case - you can just dive straight in with no problems. Well maybe an introduction mail first and then immediately dive in. Craig

Meanwhile in the UK we had the warmest February in history. Peaked up at 22C (72F) with brilliant sunshine for the best part of a week. It has cooled off somewhat since then, but any snow has been confined to the far North and Scotland. It has really screwed with nature. About ten days ago, out walking, I saw butterflies, and birds with nesting material in their beaks. A good 6-8 weeks earlier than they should be.

She is astonishing. Here is another that leaves you breathless

Happy birthday!

Wow - totally missed this! Thanks guys. Had a blast of a day. First to see a play called Just About Eve in London with the thinking man's crumpet (Gillian Anderson) and Lily James (Downton Abbey) https://allabouteveplay.com/ . Then cocktails at the Ritz, followed by an Indian meal at a 1 Michelin star restaurant in Mayfair (Benares https://www.benaresrestaurant.com/ )

What a nice present! Does it comes with the woman?

That one must have been 1973 or 1974, because that was when Disney's Robin Hood was released. The record version was a bit strange even then, because that was in the heyday of the casette tape with much longer play time.

In the 1950's 16 2/3 rpm vinyl records were pressed containing books for the visually impaired and blind. Autochangers from that era always had a speed position for 16 2/3 rpm. It was a format that did not last for long.

Hope you had a great day, Nate!

The main advantage of the 465B does not relate to performance, it is mainly due to internal design changes, and the fact that it is a more recent (1978) design. But the 465, 465B (both 100MHz) and the 475A (250MHz) have a maximum sensitivity of 5mV per division. The 475 has a bandwidth of 200MHz, but a maximum sensitivity of 2mV per division. So it really depends on what bandwidth you need, and what sensitivity you need, and that dictates your choice.

Have you thought about a turbo-trainer and using your road bike?

Have a great day Naaman!

I'm a collector of (mainly) 7000-series scopes, most of which use custom silicon. The 7104 and 7904A are full of them in esoteric Tektronix packages. I have not had a single custom IC failure in any 7000 mainframe or plugin. There are other irritating failures that crop up after 30-40 years, but no dead chips. However the 2465 and related scopes have a weakness in the IC's with an integrated heatsink. It is not a silicon failure, but a bondwire failure. I recall that there are those who can open up the IC and rebond the chip, and reassemble. For a more modern offering, cost effective, and reliable Rigol is a good call. Ah - here we go regarding fixing the hybrids in the 2400 series scopes https://www.sphere.bc.ca/test/tek-parts/tek-info.html

Last summer we were on a walking holiday in Switzerland, and on the wall in the hotel dining room was a print of this picture. It shows that love of coffee has been going on for a long time. https://www.pictorem.com/97173/An old man making coffee.html dating from the mid/late 1800's Also in Neville Shute's novel "A town called Alice" two men are talking in a London Gentleman's club just after WWII. One of them is bemoaning the lack of decent coffee at that time, and remembering real ground coffee, which must be ground no more than a few minutes before being brewed. Going back even further to Samuel Pepys in the mid 1600s mentions coffee houses in London. They were used for all sorts of purposes, often meeting places for politics and business discussions. So, good coffee appreciation has been going for well over 300 years!

Have a superb excessive time! Happy birthday!

You heard it here first

Have a spectacular day Steve!

I buy my beans ready roasted. Been through a number of artisan roasters over the years, but currently use this one https://www.monsoonestatescoffee.co.uk/

Hence the need for an artificial hand. The thermodynamics is really where the thought exercise falls down - a box that is sufficiently insulated so there is no heat flow into or from the chicken via the environment over much greater than one year? A mechanical or electrical coupling into the artificial slapping hand that has no additional heat flow? I think I'll just keep using the oven
