*THIS GROUP BUY IS OFFICIALLY CLOSED *
This is an ACA Mini PCB with artwork designed by Mark Johnson following the Nelson Pass circuit. It is very close to the artwork released by Nelson Pass for the boards which were given to some lucky participants of the Burning Amp Festival. Mark was gracious enough to produce a number of his boards and give them away: I was one of those recipients. I have built the amp using this "Almost Clone" board and it works and sounds fantastic. It was suggested that a group buy for this "Almost Clone" board get started...so here we are.
This group buy will run with the quantity limited to 50, and the time limited to two weeks, whichever comes first. We will be shipping to addresses within the continental US during this first group buy. Depending of the success of this buy there may be another and the parameters may be broadened to include the rest of the world. For now I'm trying to keep this thing as simple as possible.
Photo's of a completed amp can be viewed in the ACA Mini thread #462
Of course you will be using the Nelson Pass article for a description of the circuit, build guide, and biasing instructions found at the beginning of the ACA Mini thread #1
Cost of the board will be $12 with $5 in shipping to an address within the Continental USA.
To purchase a board simply copy the post with the current list of names, add your name and quantity, update the total, and paste to new post.
This Group Buy will end on January 22, 2022 at 12:00pm EST
Thanks for looking,
Kevin

Kevin, I think I will fix the backwards-rotation mistake and create a new revision of the PCB, called "Rev.A". The initial risky-build boards in red epoxy, were called "Prototype Rev". I'll update the schematic too, so it says "Rev.A". And I'll remove the gigantic text "EXPERIMENTAL" from the bottom side of the board. Even though one member of the Orange group of risky-builders, really loves it.
