Bloody hell - that is an insane price. And the lightweight screws that are part of the package are not metric - they only work with the supplied nuts. Don't try to use them in tapped holes in a cartridge (they will be M2.5) - the SME ones will bind and ruin your day. Try SME for the price - it can't hurt to find out. They still manufacture everything in-house. Even the screws, nuts, spacers, finger lifts - everything. The only thing they buy in is the raw tapered arm tube, which comes from Chicago White Metal https://cwmdiecast.com/ , but even then all post machining, painting, silk screening etc is in house.

I suspect you can order one from SME. It'll still be pricey, but at least it supports SME (in spite of their no-new-arms policy) rather than internet gougers.

Very hard to get my head about the fact that she's gone, so young. Fuck cancer It saw my wife's mother off nearly a decade younger, aged 42, when Carole was only 18.

RIP Sabine Schmitz, a major endurance racing driver, and Top Gear fun and crazy German driver. Died at age 51 after battling cancer for four years. Too early, far too early. https://www.bbc.co.uk/sport/motorsport/56420308

Have you actually *read and understood* the welcome message?

Happy birthday!!

That's a big knob

I've bought quite a few Linear Systems single and dual JFETs from Micross. The pain in the ass is that you have to complete and end-user form now for every damned order. It didn't used to be the case, but must relate to some change in US export rules, possibly during the administration of the orange menace. Mind you it is not as onerous as importing potentially sensitive semiconductors covered by ITAR (International Traffic in Arms Regulations), which many space qualified semiconductors are. You have to sign documents that say you will go to jail if you sell them on, or even lose them. They need to be stored in a locked location, a register of use kept and signed, and any devices you don't use must be destroyed or returned. Fortunately launching into space qualifies as "destroyed"!

The only Aavid shoulder washer that is formally intended for the TO220 package is the 7721-7PPSG, but that has a really short bush length of 0.81mm, and will absolutely guarantee flash over. ISTR Kevin used those in development of the original T2 clone, and indeed got flash over. That must be buried somewhere in the early pages of this thread.

I like that washer a lot. I used the 7721-3PPSG. That has a longer bush length than the 7721-10PPSG (3.18mm compared with 2.41mm). But 2.41mm should be just fine. The downside of both our choices is the bush diameter of 3.56mm. The tolerance for a TO220 hole is 3.53mm to 4.09mm. Which meant that for some of my devices it was a really tight fit and needed to be pressed home. On other devices it just dropped in. But they fit into the hole in the ceramic washer just fine.

Plastic screws cannot take the torque, even at the correct an surprisingly low value from the On-Semi apps note. Found that out having bought a shed load of PEEK ones, only to resort to stainless. Don't forget a smear of heat sink grease between the package and ceramic washer, and between the washer and and bracket. Where did you get the rectangular bush from? That is very neat.

I think it is a different company. http://www.qstools.com/index.asp

I have that same Lie Nielsen low angle block plane too. Then I bought a regular angle and a rebating low angle block plane by superb Chinese Quangsheng. These are basically Lie Nielsen knock offs, but are fantastically good quality with a thick iron that takes a razor edge, and needs hardly any back flattening.

First the link. Chinese - what do you reckon the chance of obsolete sand from China being genuine? And second - What exactly are you saying? Please very carefully clarify.

Well that is interesting. The killer, however, if these came from the US to the UK is (a) $18 shipping and (b) They would get stopped for VAT and a clearance fee of UKP10. So the actual price per quad is about doubled. But the same thing happens for the DIYAudio linear systems ones. All part of rip off Britain.

The key difference between a toroid and an R-core is primary/secondary capacitance and leakage inductance. R-core has primary and secondary on opposite legs. So the capacitance is low, but the leakage inductance is high. With a toroid, the capacitance is high, but the leakage inductance is low. So an R-core (like a split bobbin EI) is better for not coupling RFI between windings. But the leakage inductance means enough stray magnetic field to cause potential hum problems. A toroid by contrast, because of the tight coupling between the windings, tends to couple RF. But because of the low leakage inductance has a very low external magnetic field. Basically, horses for courses. I've used both types in various bits of my kit. But since I always use an outboard supply (for non-power amp use) either type has worked just fine.

That is taking the term "near field monitor" a bit to extremes!

Thanks guys! That was a fine day that started with a Zoom with the kids (well, 32 and 35!), and finished with an excellent steak dinner. And now - time for bed said Zebedee.

And now for something insane. The two monoblocks weigh half a ton, and in US speak around $400k . Dan D'Agostino going totally bonkers. https://dandagostino.com/products/relentless-monoblock.php

Good grief. Sounds really flaky.
