Craig Sawyers

Now *this* is a sausage (a Cumberland Sausage) Not for breakfast, but with a variety of things like onion gravy, mashed potatoes, Yorkshire pudding, chips. Or all of that in a very large Yorkshire pudding. My mouth is watering. Oh yes - Google is your friend!

That has to be an English breakfast, because there is black pudding on there!

RIP Arnold Palmer - one of the all-time greats of golf. But at least 87 is not a bad round.

Happy birthday!

I have. In Majorca. It was very rubbery.

First of all, check that part is correct for a TO220 package - I didn't spend a vast amount of time verifying it was the right size.

Found this lurking on my PC CELLO_AUDIO_PALETTE (1).pdf

Oof!

Well spotted. But then I saw the price for one that would do a TO220 https://www.seastrom-mfg.com/washerdetails.aspx?productNumber=5729-9-4

^I have the original vinyl. The cover still shocks - I cannot imagine anyone producing an album cover like that now. Saw them live in '73.

The flared part of the washer faces a plain washer, and does not bear directly on the board. Do you notice the "rectangular steel washer"? Unless someone has an obscure source, these are unobtainium.

I just followed the recipies in this http://www.onsemi.com/pub_link/Collateral/AN1040-D.PDF .

I used to be list admin for the XJ Jaguar list on www.jag-lovers.org. It had about 8000 members internationally. There were a number of parts, car modification and other vendors on the list, including Jaguar themselves. If someone slagged one of them off there were instant threats of a legal suit against the admin (me). I stepped out - I just did not need that level of threat. In fairness to HF (yeah - I know...) the list owners have to deal with precisely this, and will, or ought, to have told advertisers how they deal with what could be interpreted as libel.

I agree with just about all that. At one stage you could buy thick rectangular washers the same size as a TO220 tab to spread the pressure, but they have not been available for years. I tried M3 PEEK screws on my build, but was unhappy with the very low torque necessary to strip the threads. In the end I used a combination of ceramic insulators (as specified by Kevin) and the really long insulating bushes, and stainless cap screws, nuts and Belville washers. My T2 was one of the first batch made, with casework supplied by Kevin, and I have had zero thermal problems.

One of the reasons Krell went with variable bias was that the sustained Class A beasts (KSA50, KSA100, KMA100 etc) ate power transistors. Krell rebranded them Krell A and Krell AA to hide what the real part was (in the same way Audio Research ground off the part number of transistors and painted on a three colour code). My KSA100 blew three times, in a final last gasp taking out the drivers and their emitter resistors to the extent they burnt part way though the board. This was typical of the entire series. So variable bias was introduced, not from some kind of green reasoning, but to mitigate self immolation tendencies.

Pardon?

This happened years ago to the recently late, and very great folk violinist Dave Swarbrick. He had major respiratory problems, and used to perform using an oxygen cylinder next to him on stage. Probably smoking induced emphysema. After a chest infection in 1999 he was rushed to hospital, and The Telegraph published his obituary! For then until his death 17 years later he used to sell signed copies of his obituray at his gigs (with Martin Carthy). Because of his iconic status and failing lungs, friends organised a series of charity concerts called "SwarbAid" to raise the money for him to have a double lung transplant. Those lungs saw him through another 12 years of stage performance until his actual death (rather than his premature death in print in 1999!) in June this year at age 75. Was lucky enough to see him with Martin Carthy at the Nettlebed Folk Club in October last year, and shake his hand.

The guy who is electronics design director at NAIM is called Steve Sells. Way back, I recruited him from University into Cambridge Audio, when he was already a power amplifier designer of some capability. After a short while, we moved that into Wharfedale, where we planned to re-launch the LEAK brand. I asked him to design the best power amp he possibly could, price no compromise. I told him that we had to out-Krell Krell, and if he felt that silver wired mains power transformers were essential, he could have them (he didn't - phew!). This was a superb animal, balanced input, bridged FET output monoblocks that would push 800W into 2 ohms, each with three mains transformers (two huge ones + and - for power transistors, and a single higher voltage one for the input amplifiers). Fast forward three decades, and NAIM told him the same thing, best possible no holds barred - Statement was the result. Not for those with less than seven figure salaries. An awesome audio tour de force. Have a look at this:

You, Knucks, are on a roll! Awesome images.

Yes - the BT Virginia Woolf is massively intense. In The Burton Diaries he reckons that it was the best thing the he and Taylor did. I didn't realise until the above that it was from a Broadway play by Albee. RIP - what a legacy.

Have an absolutely great one, O tall person!

What a pioneer. RIP

RIP Sushi. Very sad to hear. 19 is a great innings.
