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 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).
