[Boatanchors] Tektronix Type W Plug-In Unit

[Lawrence Mayhew]

Sorry Glen, the numerals on the Nuvistor are not date codes. The Nuvistor
was introduced in 1959.

Hello Jeff,
The NUVISTOR Electron Tube that you have is a Type 8056 "Triode" most likely
manufactured by RCA.
The TEK TYPE "W" is an Oscilliscope Plug-In Module designed to fit the
Tektronix  500 Series Oscopes.  It is a Differential Comparator or
Pre-Amplifier Vertical Plug-in usable up to 23 MHz Bandwidth.  You could
also use it in the TEK clones such as the Lavoie LA-545 Oscopes or other
equivalents series oscopes.  You can find SIEMENS Data Sheets on this Triode
Nuvistor at Frank's Tube Data Sheets. It has a 6.3 Volt Filament.  Date Code
was May 1948.

Best regards,
