here are two manufacturers of the
voltage regulators used on 60 Hz 15-
KW, 30-KW, and 60-KW tactical quiet
generators. One is made by Libby and
the other by Technology Research
Corp (TRC).
Both models work fine, but their
individual components—T1 trans-
former, R1 voltage adjustment rheo-
stat and R16 voltage adjustment re-
sistor—are not interchangeable.
If you mix one kind of voltage regu-
lator with the other’s parts, you’ll be
Here are the components that you cannot mix:
scratching your head and wondering
why you’re getting no voltage output.
Here are your voltage regulators:
"LIBBY" components
"TRC" components
A kit containing the
TRC voltage regulator,
T1 transformer, R1
rheostat and R16 resistor
for the 60 KW can be
ordered with NSN
