Wow ! I bet it was mucho fun workin' on that puppy-everything's so cramped,built on top of itself & all. But I've always wanted to see the innards of that set- I have the later 5-303W that was responsible for so much of Sony's phenomenal success in the early '60s. Great score.-Sandy G.

What year was this built? I know that Motorola built and sold a 19" B&W solid state TV in the early 1960s to prove that it could be done. It was called the Argonaut or something similar. Even though it was billed as solid state, I bet it still had a tube high voltage rectifier just as my late 1960s Philco Ford "solid state" sets.

Motorola built their own solid state components starting in the mid 1950s.

It appears that Sony may have just barely beaten Motorola with the first non-projection solid state TV.

The earliest solid state tv that I have is a 1967 Sylvania B&W TV.

Is there a tube HV rectifier on the deflection board, next to the flyback, or am I seeing things? :scratch2:

It probably does have a tube HV rect...my 1968 Sony 5" portable uses a tube type HV rect. in a voltage doubler or tripler setup (2 or 3 tubes).
