Herbert Serial number 001/335 ???

[Plugmein]

I received an email from Peter Stapfer in January 2008. The email stated that my Diezel Herbert - 001/422 was built Oct 25 2005, or 25.10.2005. So if you were told that your Herbert - 001/334 was built May 21 2006, then the question should be, "who's keeping the past production records for the Diezel line?" It would be great if past build info could be accessed on the official Diezel web site.

The email I recieved today was from Peter Stapfer - > peterstapfer@diezelamplification.com

"Date of production: 21.05.2006

Peter Diezel knows the exact version number. I shall forward this e-mail to him right away.
He´ll give you further information next week. Today is his wedding. I hope you don´t mind that he´s not checking any e-mails today."

I thinkl it was Ed Yoon from Tone Merchants who
brought up the rumour about the revisions.

We made small changes from time to time to optimize
the circuit but there are no MK1, MK2 or MK3 versions.

We built the first 30 with woodgrills and these were
called later MK1 by Ed Yoon, we never stated about
different versions.

There is also some guy who said that we built a MK3
version. Sorry, I don´t know about that.

Best,

Peter

This being said, why so much worrying about "revisions"....?

Build dates and purchase dates are two totally different issues.

Yes, I do know that the production dates and purchase dates are different. The only issue I had was that my Herbert's production date, and King Crimson's, seem to be at odds. Both of us receiving information directly from Peter Stapfer. Personally, I don't care when my Herbert was produced, but when you resell on any auction site, the number one question one receives is "when was your amplifier built?" I just would like to know, so as to give anyone I have to deal with in the future, the correct info, on any and all amplifiers I own. I can pick up a phone and receive any info on my Bogners, Mesas, and VHT that I own without any problems or contradictions. I just would like the correct production information like any customer would. Thanks!

The anus is the most well known, and arguably the strongest (or tightest) sphincter in the body. If you are being anal, then you are exhibiting characteristics of being far too uptight.

Is it bad? Only if you are worried about your blood pressure and hypertension, having a stroke, kidney failure or forcing people away from you because you are too much of a perfectionist, obsessive, and life will not be complete for a Diezel connoisseur until one has the complete Diezel serial number description codes and revision specifications!!!

Mine is 585. It left Germany in August 2006. No way 334 was built just a few months before. I'd say 334 is a 2004 regardless of Peter's e-mail.

Yes way...

Peter starting using the external bias adjustments in the 300 range or so around 2006, then in the 700 range or so he began to feature the fault LEDs too. So my Herbert is the latest specs sonically.

Does your Herbert have the power tube fault LEDs above the fuse holder?

Ooops. Looked again. Mine is number 595, not 585. I still think you are a little off on you production dates. I did alot of research around serial numbers and production dates before I bought mine. Unless they didn't use sequential serial numbers (which doesn't make sense), I'm quite certain that 334 was made in 2004 or early 2005 at the latest.

Mine has the fault LEDs. I believe it was one of the first US shipments to have them. My amp had been on order for 6 months (in July 06 I took over an order from someone who originally ordered it in in Feb. 2006 from Tone Merchants) before I got it. I got it brand new in box direct from Germany through Tone Merchants. Earlier U.S. shipments in 2006 did not have the LEDs. I searched for a used Herbert long before I bought a used one. Based on direct communications from Peter Diezel, amps in the upper 400s were being made in late 2005 (consistent with Plugmens post above). He had told me that external bias had been around for 2 years when I bought my Herbert - so 2004 is when that started. I had given him some serial numbers of used Herberts I was looking at to check the age and specs. He said the only new spec in 2006 was the LEDs - which again, mine has and was made in roughly July/Aug 2006. I don't know of any other changes since then.

Sonically our Herbert’s are identical. After the first sonic change was made to Herbert’s PCB (which we both possess) then Peter implemented the external bias adjusters. Then Peter implemented the fault fuse LEDs. The external bias adjusters and the fuse holder LEDs were not implemented at first at the same time. Now they are both so.

BTW - I have located keyed fuse holders that match up with the 250V/500mA fuses perfectly and they have a built-in fault light.

So then, you are stating that both Peter's have given me false information?

That's all I really care to dig on this. I'm fully content with what I have.

^No. I'm not saying that they don't sound the same. I'm sure they do. The biasing/LEDs shouldn't impact the tone. I'm just wondering about the true production dates/serial numbers. I'm just stating what I know about serial numbers/production dates - not trying to say the amps sound different. Maybe have Peter Diezel confirm the production date for you - then I'll believe it. I just thinking there is no way they produced 334 in May 2006 and then were up to 595 in July 2006. We bought ours from the same dealer too.

The biasing/LEDs shouldn't impact the tone.

The LEDs definitely don’t have any impact or gravity on the tone of Herbert. Excessive cold or hot biasing will, the LEDs won't.

The LEDs are basically idiot lights (please forgive the vehicle correlation) letting you know that one or two of the power tubes in a duet have failed. It would be like debating which MIDI cable sends improved 1s or 0s to your MIDI connection device.

I wish I had a dollar for every time that I’ve been testing new power tube combinations with Herbert and have inadvertently left out a corresponding duet, only to realize after a good while of playing that I for the most part hadn’t realized it. Now that’s a big DOH!
