If it is not putting out regulated B+ @ 130 V DC it is most likely
faulty..... obviously the other supporting circuitry can cause a B+ faults
like shorted loads (always look for a bad HOT), bad pre-regulator diodes and
filter, faulty base drive/reference, open resistors, etc. The STR 30130 is
usually a fairly reliable unit as long as it is heat sinked well and the
solder connections aren't cracked or dry.... or there isn't a fault before
or after the chip.
Pin 1 Common
Pin 2 Base
Pin 3 Input
Pin 4 Output
Pin 5 n/c

Thank you for your input.

I am first year EE student and appreciate your efforts.

I have no voltage out of the regulator.

There is a relay that is not energizing and I assume that;s because
there is no high voltage.

A viscious circle.

How to continue?

No schematic .

Thanks again
