Sabaj A20h Balanced Headphone Amplifier Owner's Thread

The product numbers for the 5.5/2.5mm power supply are GST60A15-P1L or -P2L, but they're very difficult to find, or even impossible to find.

Would both be ok? The original psu uses the "Tuning Fork Style" which would be P1L.

Eine weitere Alternative wäre der GSM60A15-P1J aus dem Medizinbereich, mit 20mV weniger Welligkeit und Rauschen, aber leider auch mit dem 5,5/2,1mm Stecker.
Auch hier enden die Artikelnummern für das 5,5/2,5mm Netzteil auf -P1L bzw. -P2L. Ansonsten ist ein DC 5,5x2,1mm Buchse auf 5,5x2,5mm Stecker Adapter oder Lötarbeiten erforderlich.

It doesn't matter; both fit and work. The connection in the device is the same in both cases.

Alright, thank you also for the info about the GSM60A15, it's only 5€ more, I'll go with that then. Really want to know if this would fix the noise issues.
With adapter it comes to 31,35€ with shipping. I guess I'll try this out.

I just received the PSU. I can't do any scientific tests, but I tried calling my phone with the phone of my mom to force some noise.
To be honest, I don't know. Getting very close to back side of the A20h does make noise with both PSUs.

I guess I need to just watch how this continues and see if I don't get any random noises that happened before when there were no calls as well.
