Produces a sequence of two to sixteen programmed voltages at each of three outputs. Otherwise identical to Model 123.

DIY Resources

  • Schematics: (123 and 146 use the same circuits, replicated 8 or 16 times respectively)
  • Errata: Based on examination of an actual unit, Apetechnology reports there should be an additional 910pf capacitor linking the final stage (collector of Q75) back to stage 1 (base of Q15, mislabeled as Q16)
