Testing 130V voltage regulator

[Reece]

Due to an accident with the high voltage cable, the "zap" took out two components, the HOT and the voltage regulator. I have them removed from the board. The HOT is definitely shorted and will be replaced. I have also gone over most of the caps and resistors etc. in the surrounding "boardscape" and found them OK.

The regulator is an NTE 1777 and checks as below with the DVM set to diode, first with test leads one way / then with leads reversed:

Pins Reading
2-3 open/open
3-4 13/13
2-4 open/open

,,so it's bad. I have three used candidates to replace it that I will call A, B, and C, all are STR 30130. They read like this:

A
2-3 600/open
3-4 open/600
2-4 955/open

B
2-3 590/open
3-4 open/610
2-4 1050/open

C
2-3 590/open
3-4 open/613
2-4 1117/open

The three appear to be good to me but would like others' opinions. Did I test these correctly and do the readings look reasonable? If you had to pick one to use, which one would it be, or does it matter? Thanks!
