Buchla inspired 259 Complex Waveform Generator DIY module.

The PCBs are matte black or blue with golden solder pads. Every component is through-hole.

The full kit includes everything you need to build the module. Only high quality components from TDK, KOA-Speer, Nichicon, Xicon, NKK etc. Precision DIP sockets are included as well to make IC replacements easier.

Apart from that you will need basic things like a soldering iron, solder, wires, other tools like screwdrivers and skills 😉

MAT02 replacement = KC811 / MAT03 replacement = 2N3806

DISCLAIMER

The PCBs are sold unpopulated and need to be stuffed by yourself. Basic electronic skills are needed.

We will not take any responsibility for damages or injuries when building and running the offered PCBs or full sets.

Build notes

  1. The J201 tends to have a flat shaped sine wave. For a more accurate sine please install a selected 2N4339 instead. They are available here: 2N4339 Please check the pinout when installing ! Picture will be added soon.
  2. Add a 20k multiturn trimmer across R290A for amp-mod adjustments along with TR3
  3. Solder wires to connect the following pin: a, b, c, d, e, f, 6-6a, 10-10a. Pins g and h are already bridged on our PCBs.
  4. If Timbre is too weak, try other PN3958 or 2N3958. Trim Timbre by adjusting TR2.
