very typical of the 5062C regulator board. IF run long enough, the PCB can actually de-laminate or crumble when removed. Run very hot and little circulation in the honey-comb structure.

I pulled the 18v regulator board out and it's pretty discolored from running hot. I don't know if there is a short on the 18v bus that caused the failure, or if its the regulator board itself. I have done lots of internet searches but have not found a service manual for sale yet, only the HP Journal issue on the standard. I do have the operations manual in PDF form. Many thanks, Tim Schulz... _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
