Technodistortionsgerät

Very nice!
Which design of germanium distortion did you use? Can you share schematic?

Thanks! This uses 1N60 diodes, and some 1n4148 as well. PM me an e-mail address and I can send the docs.

Edit: Just to be clear on this: The Germanizer is copyright by my friend Fredrik S (I just happened to be in on the idea). It's OK to build for personal use only.

it is in "nuke" mode per default !
beware of the russians! (just joking, Schrabikus )

Beware of soviet diodes!

Wow! Use any you like, we sat on some extra Germanium diodes so it just felt proper. The normal Si diodes will clip at 0.7V, the Germaniums should be 0.2-0.3V-ish. In a modern construction one can get away with Zeners or Schottkys depeding on application but a Zenerizer isn't as cool, unless you happen to like the letter z.

The nuke is there simply because we needed a term for harder than hard. I don't like nuclear weapons. Or war for that matter. We must learn to get along and make tea instead.

+1 on that comment
hey, these soviet diodes above look like they are able to withstand high velocity space particle impacts for use in kosmonaut environment very nice!

Enjoy the schems! Write me back in case of questions. You can substitute the 220k pots for 200k or 250k if those are easier to source.

Just imagine what I'll do to the future front panel for the Polivoks filters

Oh, and don't get hung up about the Swedish lab notes. Those are not saying anything worthwhile. The thing as good as is

Thanks! I tried to make a few more simple circuits but was not satisfied with the result. This is what i need! =)

Will it work with single polarity supply?

Not without some modifications You can use an LT1054 plus regulators like they do in the Shruthi-1 if you want to invert a single polarity supply in order to get +/-15V. Just change some resistors if you want +/-12V.

Breadboard it first if you experiment with supplies
