Oakley Systems Wavefolder Module |
I built my WaveFolder with a Stooge Panel. I made
several modifications to improve operation with a low Gm
CA3280:
1. Changed R34 from 200K to 300K to set the Threshold range to +/-
5 volts.
2. Changed R49 and R53 from 68K to 47K to center
the Fold control.
I also made these modifications:
3. Added 1uF capacitor in series with main output
since this module can create large DC offsets.
4. Replaced R10 with a jumper and did not install R2 and R9 on the
unused op amp.

Tony emailed me this useful description of the operation of the clamp polarity switch: "I always set it up so that the switch in the upper position will cause the WaveFolder to clip the upper portion of the waveform. That is, only the lower portion will get through if fold is set to zero. I tend to think of it as being the portion that is being folded." |
