Dneu2011 Posted February 5, 2022 Share Posted February 5, 2022 For sale is a completed class A Nelson Pass designed setup I put together with matching custom designed vinyl logos. I built the Whammy and PSU but did not build the amps originally. I did, however, upgrade them and check all solder joints. Description of each piece is below: - Whammy Headphone Amp/Preamp is a Class A preamp designed by Wayne Colburne at Pass Labs. High quality parts and includes Preamp outs and a switch to go between headphone and preamp out. This can easily run low to high impedance headphones and makes a great high gain preamp. - Amp Camp Revision #1 monoblock amps. These are highly modified with upgraded schematic part changes discussed on DIYaudio forums, adjusted for 24V input, and have an upgraded PSU I built. - ACA PSU includes a torroidal Antek transformer with 200va and 20V secondaries for a steady 24V power to the amps. The power filtering is a Cap Multiplier supply that is a huge improvement over the original 19V supplies and newer 24V supplies recommended by Nelson. The PSU connects to the amps with special Umbilical cords I created. Amps put out 10 watts of SMOOTH Class A and would work well with any 90db and higher efficiency speakers, especially Klipsch. RCA input only to the preamp and only one input. Any questions, just ask. I am only selling this setup as a set. Located in Houston, TX. I am asking $800 plus ship.
