D*A*M: Dizzytron ZZ.2

I thought it was another D*A*M variation on the Buzzaround, but it turns out that it's actually an Elka Dizzy Tone, which is still very much a Buzzaround (as pointed out by Anders, AKA fuzzhead, see comments).

There's one resistor that I could not see the value of; it's likely to be 18k based on Elka values, but like most things relating to biasing germanium transistors, test it and see what works best with the parts available to you.  

Differences to the Buzzaround

  • The pair of bias resistors on the base of Q1 is odd values
  • 22u caps instead of 4u7
  • 250k rev log for Sustain
  • 1m or 100k for Attack
  • 4k7 for Balance

Some links are not shown - for example: Q1 emitter connects to Q2 base.  If you're building on tag, I'm assuming you know what connects where on a Tone Bender MKIII-style circuit.

  1. Very cool!
    Looks like Elka Dizzy Tone values?

    1. Wasn’t aware of the Elka - I would say that’s exactly what it is. Thanks for sharing that, much appreciated. Side note. New Dinosaural on Aion

    2. Elka is well worth a layout alone, sort of a more extreme version of Buzzaround.

      Dinosaural...workin on it.
