Craig Sawyers

Looking at the guest list, the only one I recognise is Susan Hampshire, the three time Emmy award winning actor. Her husband has dementia, hence her interest in Brendoncare.

This is actually for tomorrow. My wife runs https://www.brendoncare.org.uk/ as CEO. Their patron is HRH The Countess Wessex, wife of Prince Edward, youngest son of the Queen. So tomorrow we're off to Bagshot Park (their home) https://en.wikipedia.org/wiki/Bagshot_Park as a fundraiser for my better half's latest project https://www.brendoncare.org.uk/care/our-care-homes/otterbourne-hill . Dinner for 42, with five great and good expected to fork out UKP150k. The ones that could not make it, chipped in UKP10k. Should be interesting! I'll let y'all know what it is like.

Although it is a massive pain in the ass, particularly with large boards, I stuff one part at a time. And then use a highlighter to cross it off on the BOM and component layout. It just saves so much grief trying to find the stuffing error, or lead you've not soldered. Even so I've stuffed PNP's instead of NPN's recently (pulled them out the wrong tube). Took an embarrassing length of time to find that error. Fortunately low power, so nothing fried - it just failed totally to work.

Happy birthday - and get well soon!

Currently 10% of global power generation is consumed by server farms, cloud computing, crypto-currency, data centres and so forth. Google and Amazon alone count for a good chunk of that. To control that nonsense new installations are located either in cool climates (Like Iceland!), near the sea (to limit air conditioned cooling), and current plans are to site under the sea (security and having lots of cooling *right there*).

Weird shit in Ca - either forest fires or freeze. Keep calm and carry on Here in wet old UK every footpath is a sea of mud.

^ What a disaster.

That is really sad, Todd. How awful. RIP Carol.

Happy birthday Steve! Have a truly great day.

Iron the Terrible - wasn't he a medieval Tsar

That is one of the most disturbing things I have seen

Happy birthday!

Oh - OK. Geddit. I was thinking about how you could possibly know that I know Paul Messenger and Martin Colloms, or that I was CTO of Wharfedale in the early 90's. I clearly overthought your comment

Huh?

And another belated Happy Birthday! Hope you had a great one.

The solder tab on the body connects through to the cable connector shell. Unless the body of the connector is connected to chassis that gains you nothing. You need to connect pin 1 to chassis as directly as possible. Reducing the loop area is the aim of the game. To do individual grounds at each XLR you have to clean the paint or anodizing off around the fixing screws so the solder tabs at that point are shorted to chassis metal. I do that with a Dremel before I start installing hardware, so it is easy from there. It also ensures that the shell of the XLR (and hence the shell of the cable connector) is tightly grounded too.

Is that a Moog modular?

It is just that it can give rise to difficult to understand problems. Like a phone doing a cell search on maximum power, and suddenly zzt zzt zzt. The best papers I'f found on this are the Rane Notes http://www.rane.com/note151.html and http://www.rane.com/note110.html and http://www.rane.com/note166.html The nub of it is: connect each pin 1 to chassis ground as directly as possible in heavy gauge single strand wire - the goal being zero length. Even a very short direct connection inside the box is not ideal. Many professional amplifiers use a two terminal tagboard on the rear panel for + and - signal, and a screw terminal to the case. So pin 1 is grounded outside the case and shield current never penetrates the case. Pain in the ass for domestic gear where you want to disconnect it easily, but OK for permanently installed studio gear.

Who's at the wheel - Elon Musk

Looks really good! Minor point on the XLR wiring. You've got pins 1 chained together and then via a wire to chassis. And yes - pin 1 absolutely has to go to chassis, but by the shortest possible route - a separate thick wire from each pin 1 to a ground solder tag at the nearest XLR screw. With the arrangement you have, any RF intercepted by the balanced cable screens goes into a tuned radiative loop (from the dimensions, several hundred MHz) and spray it inside the chassis. And conversely any radiative interference from those class D power amps gets coupled onto the XLR cable screens.

Jeeze what a dreadful story. What an unholy mess up and such a sad and distressing end. RIP Jake.

Yup. My amps have Neutrik 32A Powercons on the back, then 32A cable to 30A NEMA connectors on a distribution block. Got to keep that mains impedance low

Did Jacobson die from liver damage? Did he die from alcohol induced dementia? No. He continued working as a freelance journalist and writer after an illustrious and prize winning career in war journalism, pretty much until he died age 79 - from meningitis. But wow - did he live a classic Fleet Street life!

Absolutely - I have a pair of LX521, which I am about to upgrade to LX521.4 . His speaker designs are absolutely awesome. They simply disappear acoustically. The LX-mini is much more forgiving of room layout, since it is a monopole and not a dipole. Someone I know has the LX-mini, and came across and we did a shoot out between them and the LX521. The only significant difference was the relative lack of bass on the -mini, which is overcome when paired with the subs. They also sounded more "forward" as compared with the LX521. But still pulled off the disappearing trick. And they are a whole lot cheaper to build than the LX521 by a very long margin. Nelson Pass has done a discrete FET analog crossover for the -mini (see SL's site), circuit boards for this are apparently going to be made available on diyAudio. SL is apparently very happy to let people come over and listen - and since you are local, why not get in touch with him? LX521's in my listening room

No - that is not what I'm saying. There is simply more than one way of skinning the class D cat, and is more to do what you have patented. And Diavelet's website is an absolute nightmare - it has more to do with production values than finding products. And they are seriously plugging their rather strange spherical speaker. They have invested 50 million somethings (US Dollars, UKP, Euro - they are all pretty similar nowadays) of investor's money in the design, so not surprising.
