  • Remarques
  • The Westinghouse Westeht was a compact and reliable high-voltage selenium rectifier assembly engineered for efficient Extra High Tension (E.H.T.) generation in electronic devices, notably television receivers, where it served as a space-saving alternative to earlier rectifier technologies within voltage multiplier circuits.

    Key details about the 36EHT rectifiers and the "Westeht" unit include:

    • Miniature High-Voltage Design: The 36EHT rectifiers are compact, housed in an insulated tube with a 7/16” diameter, and feature tag ends for easy soldering. Their small size allows them to be suspended directly within the receiver wiring.
    • High Peak Inverse Voltage: These rectifiers can withstand a peak inverse voltage about four times greater than typical selenium rectifiers, making them suitable for demanding high-voltage applications.
    • Voltage Multiplier Circuits: The "Westeht" units are primarily intended for use in voltage multiplier circuits to provide E.H.T. for various electronic purposes, such as supplying the high voltages needed in CRT televisions.
    • Space-Saving Replacement: The unit is designed to take up less space than the traditional E.H.T. rectifier valve and transformer it replaces, making it advantageous for modernising or miniaturising equipment.
    • Output Specifications: Positive outputs of 5 kV, 3 kV, and 1.7 kV are provided, with the 3 kV output also available as a negative potential, catering to different circuit requirements.
    • Multiple Models: Four models of the "Westeht" were available, each offering different output voltages and physical lengths, ranging from 1.41 inches to over 11 inches, and peak inverse voltages from 1,600 V to 19,200 V.
