Cornish SS-2 Light Drive

 With onboard input buffer. The original had two LM741s but these is replaced with its dual op amp equivalent 1458 to keep the board reasonably small

    1. Name is changed to Light Drive:-)
      Yeah, input cap is much biggrer in schem you posted but I choosed the one with 10nF input cap and 22uF output cap since it made more sense with a MXR Dist Plus input cap and a big "Cornish" output cap.

      So you built both? On Aion PCB's or from my layouts?

  4. This isn't working for me... BUT it's hard to read what's going on in this vero... 1 thing in particular the link coming from the IC under the 220uf cap is hard to see where it's suppose to go.

    1. The bottom connection for that link is connected to row M, next to the positive leg of the 220uF cap.
