This module operates from a continuous voltage of around 15 volts and provides precise heating for a wide variety of regulated DC voltage tubes.
Two distinct outputs are available:
A low voltage, high current adjustable output from 1.2V to 13V for heating common tubes.
A "high" voltage adjustable output from 13V to 60V for heating all tubes.
These outputs can be selected by a switch, with 0V as the common ground.
