New, promising Amp DIY project

[hunter]

Discovered this website today
http://www.duesentriebamps.com/

"Duesentrieb AmpsŪ is a cooperation between Peter Diezel and Dr. Olaf Krampe"

They will offer DIY kits, designed by Diezel !!

This is the site of the other dude
http://www.thinlizzy.de/

Can't wait to see their products be made public !!!!!

Nice! Diezels are awsome amps, if you can make a half as good amp out of a DIY kit, even that will be great. These DIY amps will probably be a lot more simple than Diezel's monsters, though, the VH4S for instance is quite frightening from inside. Quoting a friend - it's just like the Death Star - extremely complex but very strictly organized, lol.

I think in amplification, simple quite often gives better tone as the signal isn't affected by too many parts and up- and down- transformations ...

[HTH AMPS]

I'm curious as hell to find out what gives the Diesel VH4 that specific tone and such a tight bass end.

I'm thinking it's gotta be the output transformer since the schematic I've got which is supposed to be ch.3 of a VH4 is similar to a Bogner Ecastcy lead channel (and many others in a similar vein).

I built an amp with this topology and tweaked it to death - sounded very nice, but still not like that Diesel.

Man I am envying you that you know all this amp stuff.

I would love to just know how to bias my amps properly. But it seems there's no real good information out there on how to do it right (with unloading all compnents etc...)

Are you an electronic engineer or sth or did you just learn this stuff by yourselves?

you should read the basics and understand schematics before you do anything.  look at the schem and trace it through with the amp (or even a pedal) in question.  thats the way I started - there are many good websites around where you can learn all this stuff at your own pace.  I personally think 'kits' are pointless, anyone can do paint by numbers, you are learning nothing with a kit (imo).

start with an easy one-transistor fuzz box is my advice.

I taught myself this stuff over the last 12+ years.  Started with fuzz pedals then gradually got into valve amps doing mods and bias adjustments.

I do have a background in electrical engineering so I know basics from when we did ring-mains wiring but nothing to do with valve technology.

I'll ask for a schematic when I get my combo back from Hackman. I don't think he'll give me one but who knows... it's worth a try.

All I know is that it's NOT the power section, lol... I played both a VH4S in his workshop (I think it had 6550's) and my combo (EL84's), and although there was a difference due to different power tubes and speakers, they definitely had the same character on the 3rd / OD channel.

I'd definately be interested in seeing what makes the VH4 sound the way it does.

If you get a schematic send it my way (please).
