Anybody know the whereabouts of Alan Kimmel?

Hiya folks,

I've mostly been hanging out in the Pass Labs forum lately, but I've also been a big tube nut for many years, now. I remember falling in love with and subsequently purchasing the Alan Kimmel designed Mu-stage driver upgrade for my Dynaco ST-70. I really dig the concept, and I've been wanting to build something like the Mu stage Mic preamp found at:

http://www.taosnet.com/f10/micpre.html

Unfortunately, Kimmel's TubeLabs webpage has been defunct for a long time, now, and it bums me out. I imagine he's busy designing or teaching or something, but it'd sure be nice to pick his brain sometime in the future when I have some homebrew design actually on the drawing board.

I do console myself with the fact that people here have a tremendous amount of experience to share, too. So it's not the end of the world if he's unavailable these days for comment.

Just wondering if anyone knows.

-Erik.

Perhaps this is what you are looking for?

Thanks Hugo. I'm familiar with that one. That's where I found the Mu Stage Mic Pre schematic. But Kimmel's own website, called Allen Kimmel's Tube Audio Laboratory which used to be at:

www.ratiocinari.com/TubeLabs

and also at:

members.aol.com/tubelabs/

have both been defunct for a while, now. His site was chock full of goodness about Cathode Followers, Mu stage mods/variations, etc...

It'd sure be nice to see him put up another page.

If you want data on mu followers, also look at Gery Pimm's pages. He has lots of brilliant CCS designs that can be used for mu's, tube, sand and hybrid.

You are correct.
I was a bit too fast on this one.
Have another search, I recall seeing a mail address from the man, but can't find it anymore.

Hi

Welborne Labs has in the past used designs from Kimmel, and I would imagine that Ron Welborne would know his whereabouts. You may want to post on the Welborne Labs forum. I have a V.35 amp using the Kimmel circuit.

Hallo Erik,

Last I read about him was just before the SF Randall museum meet. Apparently he was working on something with John Atwood of One Electron. Why not mail John and ask him...

Cheers,
Bas

Alan Kimmel has recently designed for Grommes and Modwright.
He is probable currently in residence at neither business, but they might be able to forward inquires.

His Grommes PHI-26 is, to my ears, beyond remarkable with 6P14P-EV's rolled in.

The Wayback Machine at http://www.archive.org/ may be your friend here. In 2001, he added a robots.txt file to prevent crawlers from archiving his site, but prior to that there are pages in the archive that you can access.

Gary Pimm took down his site quite a while ago as well, I was momentarily heartened by Brett's post only to be disappointed when I found it still points to an empty page.
