This is how the Rubycon Black Gate caps where lost, as most here are aware. Rubycon could make more money using the line position and time for some other product, so they shut the production down. What is needed, is a manufacturer who has lines (production positions) with this aspect in mind as the actual original implementation point. Of course, this ends up being only a high end consideration due to costs.
Folks (end buyers), in general have little idea of the costing considerations and how this quite rudely affects final retail pricing. When contemplating this issue at the actual individual parts manufacturing level, the multipliers end up getting into the 20X range by the time it hits retail $ numbers. Ouch.
Due to the loss of that manufacturing, I have felt that such capacitor design considerations are now 'fair game' and have contemplated designing such an electrolyte and similar considerations. The coatings engineer in the factory, his original work was with designing magnet wire enamels, but he now makes acrylic water based paints, with very complex particle considerations, with regards to charge, dispersion, temperatures, etc. This means I think we might be able to futz our way into designing a quite decent sounding electrolytic cap. Relatively speaking..duracap is just down the road from me. http://www.duracap.com/index.htm
Time, time, time, it's always the time thing.

In the end there are reliability issues related to different coeffcients of expansion, someone has to eat the failures. I seriously doubt that Krell had a full custom package, custom tooling can go 250k and up and many places simply can't be bothered to switch tooling for one customer. There are copper lead frames available for heat related issues though.
Can you imagine the high-end audio world agreeing on the 'ideal' package?

Mr Curl,
Mr André is (used to be) a scientist guy, you're welcome to invite him over for lunch at this dumpster.
What did you think of his 6-case Signature Six (sounds prettier in French) preamplifier ?
Thank you, John. I have already started a thread about a complementary-symmetrical new DIY preamp, with BJTs, as it is so difficult to get the JFEts. I have been just finishing PCB design, listening to the breadboard prototype, preparing documentation and proceeding POs, so I have been quite busy. I will surely join here in any reasonable circuit topology dicussion. I wish I had a chance to hear Blowtorch one day, but I am afraid it is an unrealistic wish.
Please don't forget that I asked, PMA. That is the important thing. I will stick with fets, as I have a lifetime supply. I have lots of bipolar too, but only Charles will convince me to use them by example. His circuits are still secret, just like mine are. (and you people think that you are getting SOTA, HA!)
I don't mind giving, and do my best to, within the bounds placed upon me by external (from my immediate person) considerations. My problem is where the proffered goodies are ripped from me, and then dragged off elsewhere to consume and or utilize for personal or business ventures, and little to no recognition of the origins are ever noted. One gets tired of having their fingers ripped off..and then being called an egotistical hot-aired liar.

Not true, I have it on good authority that they were simply
custom labeled, which Motorola also did for Threshold.
If you wanted copper, TI used to make TO-3's like that. I've
got a few, and they are sweeet...
There are a fair number of folks here in manufacturing, so I think this is decent place to mention a relatively new wrinkle in the money markets.
In the recent past years, a common point when traveling is the idea of money on a CC being 'put aside' for you hotel rooms,etc. Drawn on the card. The banking and credit systems have been using those sums a giant slush fund for additional credit, which is why they only reluctantly pursue any inquiries about the individual instances and will not tell you whom the culprit drawing on the card-actually is.
The current slimy development in the current international economic crisis, is the now holding back of the bank drafts for the full stated possible 10 days-and more-, to utilize as ACTUAL cash for other uses. This amounts to a full extra whatever (figure out the # if you want) # of days of cash flow for the bank, over the given year period. This slimy behavior is just beginning to emerge...so watch out for it. We've been hit with it for the past few transfers/drafts as of recent. I have no reason to believe it is personal and conclude it might be general, which is indicative of slimy behavior. I mention this as it might be happening in general, in this industry due to the business sizes, overall. A warning of potential issues in your near future.

It's not new at all. I ran into all the time it during the Lovoltech buy. I had people mailing checks on the same day as bank transfers were initiated. The checks arrived first (from all the way across the country).

Actually, it is slightly different. Those 'pre-drafts' are just an artificial lowering of your credit line. No monery is being transferred; you do not incurr any interest due on those amounts either.

Yes, clearly you can keep a running 'zero at end of month' balance and never be charged any interest. OTOH he holding of electronic transfers is real and in fact if you want a cashiers check that is immediately negotiable you might be charged several days interest.

Yeah. KOVACS is more your type. 😀

The original brilliant one. Watch the DVD collection and see how much was lifted from him.
