Raytheon 6SN7WGT Tube 1950s Brown Micanol Base Black Plates D-Getter Tested Strong

Offered here is a genuine Raytheon 6SN7WGT vacuum tube, manufactured in Newton, Massachusetts during the 1950s. This example features the highly desirable "WGT" military specification (War Grade Tough), denoted by its rugged construction designed for superior reliability and low microphonics. The tube presents in excellent physical condition and includes its original Raytheon branded box.

This specific specimen is distinguished by its classic black ladder plate configuration and the signature brown Micanol octal base, a feature often associated with lower dielectric loss and improved sonic clarity compared to standard black bases. It utilizes a D-getter structure typical of high-quality 1950s military production. As a direct military equivalent to the VT-231 and an upgrade to standard 6SN7GT types, this tube is a preferred choice for audiophiles seeking the robust performance of vintage military-grade glass.

The tube has been tested on a professional tube tester and results indicate it tests strong, well within the "Good" range for mutual conductance and emission. It offers the standard high-performance electrical characteristics expected of the type: a heater voltage of 6.3V, amplification factor (µ) of 20, and a maximum plate dissipation of 5.0W per plate.

Technical Specifications:

• Type: Double Triode, Octal Base

• Heater: 6.3V @ 600mA

• Max Plate Voltage: 450V

• Transconductance (S): 2.6mA/V

• Internal Resistance (Ri): 7.7kΩ

• Base: Brown Micanol

• Getter: D-Getter

This Raytheon 6SN7WGT is an excellent candidate for use in high-fidelity audio preamplifiers, phase inverters, and driver stages where stability and tone are paramount. It serves as a premium replacement for any circuit requiring a 6SN7, 6SN7GT, or ECC32.
