Good Luck and and that it a pretty sweet looking TV, I've stumbled upon many old Sony B & W TVs on FB Marketplace (some of them from the 1950s or 1960s) so older Japanese Sets are still out there you just have to keep an eye out for them.

Vertical output tube is a possibility but not really something I consider worth checking as long as the set is on original parts. Much more likely the papers were leaking/shorted and causing the circuit to not oscillate.
I have a fairly sizable collection of early Japanese import electronics, but I don't think Japan was exporting to us at the time this set was made. The earliest sets I've seen made for the American market came later in the 50s and into the 60s.
Last night I restuffed the doubler electrolytic. Turned out to be a lot more labor intensive than I was expecting - it was still full of electrolyte paste. And actually it still tested "ok" on my LCR meter, but the fact it leaked through the vent means it was probably not long for this world. Ah well. An hour of digging out capacitor material later...
