Oscilloscope DC Power Supply

Power supply for the Cathode Ray Oscilloscope.

Low voltage power supply with four outputs primarily intended to simultaneously supply power for the Teltron line of electron tubes and Helmholtz Coils, with four independent, adjustable DC voltages. The DC voltages are stabilized, regulated, floating, and galvanically isolated from one another, in addition to being short circuit proof and secure from external voltages.
