The Power Supply Unit of the Stabilock 4031/4032 is robust for that complexity.
But if it fails the repairing is not as easy as thinking. And the obsolet parts of the first issues
can let it be unrepairing. So I build a PSU from industriell components with a adapter pcb.
It is build from a 5V/15V 60W PSU from (now obsolet) Sunpower, and a 15V 25W PSU from Meanwell.
So you must look for a double Volt Sunpower replacement PSU, typical Meanwell, etc.
The 3 spacers can be recycled. You can recycle the 32 pin connector too,
or you can buy a new one (Harting 09041326921) to save on desoldering.
!!Now you can order a professionell manufactured PCB!!
