Dove right in! Help with RCA 21-D-8628

My process for testing unknown transformers is to connect the winding I suspect is the heater to 6V from a powered known good transformer (and measure voltages on the unknown transformers windings)...that way if you pick the wrong windings to power on the unknown you should not be over volting it by a dangerous margin.

I have an AC/DC transformer that can run 3-12 volts, I use it for testing other electronics/game systems/devices that need DC current.

Probably not what you mean. This is the first object/appliance that I am doing this kind of work with. I do have an RCA UHF tuner from 1952 that seems to work well. I can match the output signal to a digital tuner and the channel goes from snow to black accordingly. There are tubes in it that require 6v, is that assumption correct? Therefore I may be able to piggy back off of that.
