PSU5 and PSU10 can be upgrade to cut off rail voltage if there is DC offset or overcurrent on amp out...

There is no relay contact on amp out, transistors for regulated psu in PSU5 and PSU10 can switch (cut off) rail voltage without any mehanical contact.

I'm attaching my Sprint file for the regulated PSU. It has tabs for different layouts using straight bridges.
