nothing special good or bad, as mentioned tube based TV's are no where near as reliable as solid state stuff, but then again not a lot of parts and not hard to diagnose if you have a scope. The problem is the TV signal packs a lot of info on it, and demodulating it is very different with 3 things going on (AM/FM/PHASE) add to that then need for exacting sync esp on the color means more challenge but then again more fun when you get it right.
I see a brightner in there, hopefully the crt is not toast but if it is they are not hard to come by.
I would suggest a slow start up with the horz out and the vert out tubes removed from the circuit. Monitor the B+ and variac it up slowly (this assume its been out of service for some time). If the B+ comes up (should get to about 400v). then go ahead and plug those output tube in it, put a ma meter in series with the cathode lead of the horz out (you don't want more than about 220ma max) and to a full power start up.
This establishes a base line operating condition for the set, from there you can determine if any of the systems work and contcentrate on those that do not.
things to avoid, mass clean up, maggies will have a lot of slimy goo on the all the wires that interconnect the stereo/tv/speakers. there will be a lot of dust all over the chassis. Do not clean this up until after the baseline. If it works do not clean it anyway, a dirty chassis pcb that works is better than a clean one that does not.
If the dirt really bothers you, clean as you go so if a new problem pops up, you can go back to where you just cleaned. this is the same as only doing a cap or two at a time vs a shotgun recap.
the most likely issues will be vert defection and maybe power supply caps.
Often that era can caps are fine so hold off on replacing until you know they are a problem. There are lots of resistors/small caps/wires all tucked in tightly to the can lugs, so what I do is if the cap is bad, just saw it off from the top, drill holes thru the base of the can, install caps (radial thin work best) from the top and you leave the lead dress below untouched.
the vert deflection caps have a hard life, look for 1000-2000v rate film types in the feed back circuit. they get leaky and foul up the process.
