The Thyratron 395A/3985 valve, a vintage gem from the Western Electric NOs (New Old Stock) series, is a testament to the ingenuity and craftsmanship of the past. This Thyratron, specifically model 395A, is a gas-filled, high-voltage switch tube, designed for applications requiring fast high-current switching.
The 395A thyratron tube features a cylindrical glass envelope with a metal base and cap, housing an intricate internal structure. The primary anode is made of tungsten, with a filament wound around it for heating. The cathode, also made of tungsten, is located at the bottom of the tube. Inside, a mixture of high-pressure inert gases like neon, argon, and helium fills the tube, providing the necessary ionization for the electric discharge.
The 3985 thyratron, a variant of the 395A, is similar in design but has a slightly different anode geometry, designed for specific applications requiring slightly different electrical characteristics. Both thyratrons operate on the principle of triggering an electric discharge between the anode and cathode, which allows the tube to switch large currents almost instantaneously.
These Western Electric NOs Thyratrons 395A and 3985 are highly sought after by collectors and hobbyists, as well as professionals in fields such as radio technology, vintage electronics, and high-voltage electronics. Their unique design, historical significance, and excellent performance make them a valuable addition to any vintage electronics collection or restoration project.
