Sensibly equivalent to:
6L6WGB 6L6WGC
    
Extras ▼

 

This valve continues the 6L6 family, and has a glass disc construction that is fitted to an octal base. It is a reasonably powerful audio beam tetrode and was used, primarily, for audio amplifiers.
The valve is electrically equivalent to the 6L6 but is of a squat tubular construction. The cross box anode obscures the other electrodes but is obviously designed for good heat dissipation.
The 5881 was manufactured in the USA by GE, RCA, Sylvania and Westinghouse, our exhibit will have rebranded to Pinnacle.
The wide glass tube envelope is 33 mm in diameter and, excluding the IO base pins, is 72 mm tall.
