8056 Description

Short technical summary and product information.

The RCA 8056 is a Nuvistor triode vacuum tube designed for low-voltage applications. It operates with a 6.3V heater and has a maximum plate-to-cathode voltage of 50V.

This tube is known for its use in various electronic instruments, including several Tektronix models such as the 422 Oscilloscope, 502 Oscilloscope, and various plug-in units like the 10A1 Differential amplifier plug-in.

While not directly interchangeable due to voltage ratings, the 8056 shares a pinout with the 7586 Nuvistor triode. It can sometimes be substituted with an MPF102 FET in certain applications.

This component is part of the Nuvistor family of vacuum tubes, characterized by their small size and rugged construction.
