I now politely suggest that we nudge this thread back to its original topic: The (now discontinued) Neurochrome HP-1. Questions related to the HPA-1 would fit better in the TCA HPA-1 review thread.

No. The HP-1 reached down around 900 nV RMS noise floor (20 Hz - 20 kHz) so whatever noise on the power supply wasn't making into the audio band on the output.
The HP-1 does pop up on the used market on occasion though. There weren't many made, so the odds are low but not zero. Best of luck in your hunt for one.
Thanks, however im specifically looking for HP-1, in a way its a rare collectible now, that should tell a lot about you and your design. You have my highest respect for your work.
