1971 zenith 40BC50 solid state set--has ANYONE EVER seen one??

[rca2000]

A number of us here have either had--or have--some of the early solid state Zenith color sets with the flat, horizontal chassis, like the 25DC56 or 57, or 25EC58, or even the 1972 25CC55 chassis. Like most of the metal flat chassis Zeniths....ALL of them can be made to be relaible and produce a BEAUTIFUL picture.

But what about the 1971 solid state Zenith--the "40BC50" chassis?? I have NEVER seen one--and do not even know if they were sold for other than a 'field test" or such. One of my old Zenith manuals talks about the chassis--and it looks to be a LOT like the 25CC55 and 25DC56. But---in ANOTHER manual--for the 25CC55--it says the 40BC50 was NOT made in large numbers!!

Anyone here have any ideas??
