Description:

Fine 5V4G / GZ32 RAYTHEON, authentic American production Made in USA from 1956, characterized by the fascinating ST Shape bulb, robust Black Plates, and the characteristic Bottom D Getter, a configuration representative of Raytheon's 1950s productions.

The manufacturing code 280 604 identifies Raytheon Manufacturing Company and places the production in the 4th week of 1956, confirming the American origin and the precise historical placement of this specimen. The classic ST shape and typical vintage internal construction further increase its interest for enthusiasts and restorers of vintage tube electronics.

The tube has been accurately tested in our laboratory using the Funke W19 Tube Tester, obtaining a VERY STRONG classification. Both sections measured 78 mA, showing excellent balance and perfect uniformity of emission. The behavior was strong and stable, with no fluctuations, shorts, gas, or other detected anomalies.

The 5V4G / GZ32 is an indirectly heated full-wave rectifier, appreciated for its reliability and power supply characteristics in equipment designed for this type. Raytheon's American productions of the 1950s are particularly interesting for their robust construction and the quality of materials used.

In compatible audio electronics, the choice of rectifier can contribute to the power supply behavior and the overall dynamic response of the device. This Raytheon Black Plates therefore represents an interesting solution for hi-fi amplifiers, preamplifiers, tube power supplies, professional equipment, and vintage restorations designed to use the 5V4G / GZ32.

The tube is Vintage, accurately tested, and perfectly functional. The aesthetic conditions are excellent, with well-preserved silk-screen printing and minimal signs of time, and it is supplied in its original box.
