Hi all!
I've just finished my Dual G1176 with Mnats PSU. I've already built a fully-working single unit with the inboard PSU.
My problem is: Unloaded, the PSU give me on the first rail: -10V and +30V on the second, as needed.
When loaded (with any of my two main boards), the -10V remain, but the +30V drop to +5v. The LM317 is becoming very hot.
I observe the same with or without IC's and transistors.
My first question is: With Mnats PSU, do I need to stuff the board with IC's and transistors to get the good PSU voltage (when loaded)?
My second is: I re-checked severall times the resistors values and the caps orientation on the main board. How could I pursue? Since both boards are faulty and stuffed together, it's probably more a bad component than a short...
Thanks for your help.
