Old voltage regulator from the old vacuum tube days.
Pulls from equipment a long time ago but I know these were tested and then boxed, abandoned to the mists of time!
Miniwatt box but inside is an NEC VR150
Gas discharge tube that usually runs with between 5mA and 40mA, maintaining a constant voltage of 150V plus/minus 3%
Tested as described in the description
This item is not returnable, UNLESS not as described
