Thanks!
I managed to get all PSU´s up and running.
Bad Volt regulator and a broken Power Resistor.
Also noticed that the Logic Supply for the Ultimation Faders had either one of the pins in the SL668G chassi contact wrong or at the cable contact
According to the manual its suppose to be 3 wires for -15 and +15 but my system only has 2.
But the -15v has pin S,T connected on the chassi contacts but R,S on the cable.
So now it's only one wire for -15v, but maybe that is enough for 66 Faders??
+15v is correct.
Computer tomorrow that still won't boot
and after that I will start to go over all channels.
For PSU, probably small regulator board is out of order.. (I saw a lot of transformers broken/shorted, with small picofuse blown also on regulator board) Next thing is to check capacitors on small regulator board..
If one regulator board is not working, PSU shut down that +/- rail..
If you have problem with some channels, or cards..I can help with that.. I own complete test workbench for 4/6K.
