Nice job. Those are among the best-performing 7-inch TVs. While you're at it, I'd replace the remaining wax paper capacitors for peace of mind.
It's not unusual for an old picture tube to improve somewhat when it is first used after a long dormant period. Sometimes they initially look almost dead on a CRT tester, but "wake up" when you supply them with filament voltage for a while.
Enjoy!
