ACP+ (Amp Camp Pre-Amp + Headphone Amp)

  • 1900

This is the ACP+ (Amp Camp Pre-Amp + Headphone Amp) PCB, as built at Burning Amp Festival in 2019.

A ground plane is also available for purchase so that you can build it naked just like they did at BAF (if you're into that kind of thing).

If you would like to purchase both the pre-amp board and the ground plane, please add both items to your cart.

Dimensions of both boards:

8" (W) x 6.5” (L) or 203.2mm (W) x 165.1mm (L)

This product listing will have more more details added in the coming days.

About the photos

The completed ACP+ shown is an example of how this project can turn out - it's up to you to choose, procure and assemble your own ACP+.

The photos were taken by Patrick of Thuss and Farrell. The parts were all chosen, stuffed and soldered by his 10 year old daughter, Poet.

ACP+ very good preamp - excellent headphoneamp

I built the ACP+ and was very curious if it will beat Waynes LineStage and the B1 Korg NUTUBE-pre?
There is no winner! Built them all! The ACP+ is a very good sounding preamp. I like it especially as a headphoneamp.
The pcb is well made and big size. Add to buy a matched set of P-channel-JFets (LinearSystems) from
the DIYaudiostore and you have a very good basis for an excellent sounding preamp.
Thanks to Nelson Pass to offer this design to the community!
Thanks to the DIYaudiostore -team for the perfect service! Super fast delivery!!!


Great design, layout and board. I’ve been spending more time with ACP than any of my other pre’s - it sounds fantastic. Probably the best HPA I’ve heard too.

Great quality as usual.

I only purchased the bare pcb, great quality and delivery time was good for Covid restrictions. Would recommend any of the store products to any purchaser - especially the kits for the beginner or novice builder.
