1954 Availability Classification Of Marconi Valves And Electronic Tubes Booklet

This rare little booklet is a 1954 Availability Classification Of Marconi Valves And Electronic Tubes Booklet

Comprising 18 pages, the instruction book is intact but has yellowed with age and is slightly grubby with some foxing. Someone has left a footprint on the face of the booklet!

Originally owned by the Technical College, Brighton, it was provided by Marconi's Wireless Telegraph Co. Ltd to guide radio designers as to the availability of Marconi valves in 1954. A CV list was provided and other manufacturers' equivalents.

Approximate Size (Width, Height): 15.4 x 22.5 cm

A nice piece of early radio broadcasting history!
