FYI that era of set often does not need a lot of work to get going. The main thing you want to watch on power up is the cathode current of the horz out, use a bypassed analog meter is best. Monitor the HV at the anode, and the AC line current (my variac has a AC volt and AC current). Typical current at the line at 117v is about 3.5amps
watch the cathode current on the hot, you dont want it to go much over 200ma, watch the HV you dont want it to go over 25kv. I generally pull the horz out and the vert out tubes, and then do a slow monitored power up, checking the filter cans for heat, while monitoring the B+, I variac up slowly watching the AC current and stop when the B+ hits about 400vdc. I generally turn it up about 10v every 30 min or so, all the while checking the temps of the cans. If all that goes well then put the horz and vert out tubes back in and do a full power start up. You dont want to go slowly with the horz out in in place.
If the HV starts to go over 25kv pull the plug same with the current if it goes over 220ma just pull the plug.
Welcome the the wonderful world of color.
My guess is the set will work just fine, maybe a shorted tube or two, often not enough to really keep it from working somewhat. these sets are not the headache cap wise that your 40's and 50's sets are.
Mostly dirty controls, and sometimes corroded wires.
