Aging phosphors, no probe.... this is not encouraging and certainly does not inspire confidence.
BTW, brightness and contrast are important and are not a matter of personal taste.
Thirty (30) foot-Lamberts or 103 candela per square meter is the spec for 709 for overall emissivity and black point (which can be subjectively set with PLUGE, but not scientific) can be dependent on your room ambience.
Yes, it is possible to convert a household kitchen or bathroom into a surgical theatre, and the advantage is that you get to bury the casualties. Big bucks to be had if you fillum the procedures.

There are no magic numbers you can punch in to achieve calibration.
Is this a computer CRT...? Get a calibration puck and start from there, set to D65 and calibrate to bars, also use blue only (you won't have blue only as an option if this is a computer crt) (unless you are feeding from a mxo/mxo2)
generally no matter what you're dealing with, calibrating to bars, setting to D65 (some don't have this option and will require you to figure out which color temperature gets you closest).
and if possible, blue only.

"...and if possible, blue only.
Doing this would get you pretty close. "
As in... Hawaii is a sovereign state of the Union, so it must be "pretty close"?
There is pretty much no way to set the overall light output without a calibrated probe. Well, you can turn it up until it just starts to "bloom" and then turn it down a bit... maybe a ballpark you could lose the Titanic in...
There is a fallacy in "calibrating" a monitor with blue-only. It helps, a little, for setting phase and hue but has absolutely nothing to do with colorimetry, you know all those other colors that aren't 75% saturated yellow, cyan, green, magenta, red and blue.
