Postwar American Television

Home Made Protelgram

This is a closeup of the projection assembly

 

 

(1949 - 3 inch projection tube)

This set may be home made. The cabinet is very well made, but appears to be one of a kind, and not mass-produced. The chassis contains a Protelgram projection assembly. The set projects its image on a separate screen. We would appreciate hearing from you if you know anything about this set. A focusing device was sold by Philips to set the optical focus.
