  1. if by "extremely rare" you mean "the most common", then yes that is an accurate description.

  3. Thanks STG. I updated the post. I forget the revisions and numbers of each.

  4. I didn't read it as the item itself was extremely rare, but rather a rare offering of the board. And i would also guess that the latest version of the oscillator board is "the most common"...just sayin'

  5. I checked the AH list to see how many revisions there were and how they might rank as far as numbers. The following came in:

    "At least three:

    1. Discrete - on the early RA Moogs and maybe some others.
    2. Mostly discrete with 3046 array + temp co resistor
    3. Op-amped with heated uA726 array (after s/n 10175)

    The additional octave buffer board was added towards the end of the second revision.

    Followed by:
    "- Orignal osc board (2N4058 expo) up to SN 1236
    - Second osc board (CA3046 expo) from SN 1237 to 10174
    - Third osc board (ua726 expo) from SN 10175 onward

    I'd guess that over half the CA3046 boards have been replaced by ua726 boards but that is pure speculation.

    Not sure which board that is in the pic.
