"Janitorial Supplies"

Universally applicable, floating, high-voltage power supply with built-in, high voltage resistant transformer to supply the heater voltage for electron tubes. Continuously adjustable high voltage, safe to touch, with passive current limitation and analog voltage display. Unit poles can be connected to protected earth, but it is not center tapped.

Essential supplies to build and measure electric circuits.

Eliminates the Need for a Separate Power Supply

Build five different power supplies by connecting clip leads to one of the five color-coded terminals.

Basic apparatus for providing contact, power supply and support to a germanium crystal on a circuit board in experiments on the Hall effect or on conductivity. Includes an integrated, adjustable constant current source to provide the current through the sample, a measuring amplifier with offset compensation for Hall voltages and heating to raise the crystal to as high as 170 °C, also featuring temperature regulation and a switchable display showing Hall voltage, sample current, sample voltage or temperature.
