  1. Wow! That's one really nice looking Buchla. The only thing I have at the moment in terms of a video is something recorded yesterday with a partially wired up panel. It only showcases the oscillators and the wavolver.

    I'm setting up a Vimeo account, but some work remain before the machine is fully working. There's no demo yet fit for public consumption.

    Thanks for your praise, it warms me seeing it comes from one of the masters.

  2. Note: To put it more specifially - the input is AC coupled through C13 and C14. The opamps are standard TL074 so they go from -15+1.5V (-13.5V) to +13.5V or thereabouts.

    You'd have to have a DC coupled input, plus some kind or rail-to-rail opamp instead. Go with TLV2374 if that's what you're after flowers.png

  3. Not without some modifications :hmm: 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 :thumbsup:

  4. 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 :whistle:

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

  5. 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. :hug:

  6. 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.

  7. Some people think I had a plan. From the beginning it was very loose, so invention was needed as it progressed. The MB-seq made it all come together :sorcerer: Fussylizard did the bulk order and it rocked!

    The plan then:

    Looking back, plus *really* good music (as always from this guy):
