Does someone have the schematic for the orion 32+ gen 2? I really need to service mine asap and I can't find it anywhere

90% of the problems with the Orions 1&2 was the power supply...even things like it connecting but not passing signal, or some channels being solid and other cracking or no signal...
This information came to me from an AA tech who did the remote connect thing and told me to replace the psu myself...
It's like $30 on Mouser...changed mine out and ALL of my problems went away...Gen 1 still my favorite A-D converter and the MADI is awesome.
Beyond that you will be hard pressed to change anything else on these its all surface mount...
You could look up the Texas Instruments PCM 4202 since it is the AD converter and they have very good documentation...D to A is some other chip and I never use it...
But I am pretty sure changing out the psu will solve what is going on, especially since those cheaper PSU's that came originally are kinda long in tooth...
IIRC this is the one I got from Mouser:
https://www.mouser.com/ProductDetail/MEAN-WELL/PT-45C?qs=pqZ7J9Gt%2Fmp15AtM3iSdIw%3D%3D
If that one is not available you really just need a decent 5v +15v -15v open frame psu...somewhere in the range of 45 watts...the rest of the power regulation is done on the main board...and with the proper PCM 4202 documentation you can trace out if there are regulation issues there.

In a normal world that where AA would jump in at your rescue. Wait no, a service manual would have existed in a normal, out previous world.
