DIY replacement PCB inspired by a 1998 MK1 AP2 Way Huge Aqua Puss. Using my own unique layout design, the PCB can be a direct drop-in replacement to the widely available Mk2 enclosure, original Mk1, or a Hammond 1590BB. Designed to use an MN3005 BBD chip, per original. Attached are reference photos of a completed build and a comparison with an original Aqua Puss.


The purchase comes with:

  • 1x Mk1 AP2 Replacement PCB (unpopulated)
  • 3x 16mm/24mm potentiometer up-down-converter isolation PCBs.
  • 1x Faceplate for 1590BBS Enclsoure

Populated pictures are examples of the finished product using the BOM.
