Personally I like the convenience of a B&K 1077B Analyst. With one you can substitute a Video IF signal and compare that picture with with what you get connecting to the antenna. Basically you'll be able to substitute signals starting at the CRT and work your way all the way back to the antenna. The catch is these units may also need some repairs made to them. But they are relatively common place and also quite inexpensive if you can find one from some place local to you. Quite literally no one needs them today other that a handful of us hobbyists, so there's no good reason they should be anything but dirt cheap, or even free for shipping.
looks up " B&K 1077B Analyst"
I remember that thing!
I used to work in a TV repair shop late 90s and the owner had one, it was not used much , but I DO remember the CRT inside in front of the weird pick up tube that you put cells in front of for display output.

and there are some on e-bay
perhaps when I get my tax refund


and true about the tuner, I'm pretty sure that trying to replace anything in it would do more harm than good.
There Used to be someone within 50-70 miles from here who fixed/ rebuilt them, but they have not been heard from in some time. "quality tuner service" out of Longview, TX.
