I have a mogul base 3 way socket from an old floor lamp from the 1950s and a mogul base 3-way light bulb that's rated 100-200-300 watts, I could probably wire that up as a dim-bulb tester and just turn the 3 way socket on to the various wattages until the bulb dims when the set is on when it has been recapped, to check proper working order of the set.

200-300 watts would be too much for your set. I wasn't really serious about the 3 way. Like OC suggested just try different wattage bulbs starting with a lower wattage. A lower wattage bulb will have higher resistance than a higher wattage, which is why it will drop more voltage and provide a softer start. But if it's too low it also won't allow the TV to get enough voltage.

I also have a variac, but its currently not wired up, it needs a box, an outlet and a power cord. Anyone have instructions for wiring up a variac?

Pictures of the variac in question posted below.

The directions for wiring are printed right on the back, no?

Here's a pretty good tutorial on how the dim bulb tester works.

Yes, but I don't know whether or not a regular duplex style outlet would work with this variac setup or whether I would need to use just a single outlet for this setup, and I don't know whether or not this particular variac would support grounded wiring (grounded cord and grounded outlet), and how would I go about marking the voltage calibrations on the box for the knob once I got it wired up and installed in a box so I know what voltage I'm on when turning the knob.

I already have a general idea of how a dimbulb tester works, I just wanted some instructions on how to get my variac going so I could use it in the future, because I've never owned or used a variac before let alone wire one up from scratch before so that's why a little help would be nice in getting me started on wiring up my variac and getting running properly.
