Be especially wary of the IF tubes. The frame-grid types are rather touchy and when they're weak or gassy, they make it look like an alignment issue.
Also, make sure the three IF tubes are in the right socket and no one substituted one, with a close type tube.

99% sure its Toshiba. Even has the chassis tag were the TAC number
would be. Also lots of round chassis holes.
IF are 4EH7-4EH7-4EJ7 ala Zenith. High parts count too. Didnt see
many of these but the next generation saw LOTS of. They were a
bitch to work on so sprung for jig cables & pulled the chassis on
most of them. A bit unreliable but would work quite good between
repairs.
