The tester was made by Superior in 1951 and is not related to Eico.
Here is a 'review' of the device:

You probably have no fear of getting shocked with this instrument since you are plugging tubes into it for testing and not connecting it to anything else.
If you want an isolation transformer you can usually find something on eBay.
I'm guessing here, but a Triad N-51M isolation transformer is rated at 0.3 amps and 115 VAC in and Out.
This might be adequate for the tester but you'll want to look for the current and voltage rating printed on the tester, and you will want an isolation transformer of at least the same rating.
You will have to build this particular transformer into a box and add an AC plug wire and a socket to make it plug 'N play. Or you might be able to install it inside the tester. Will depend on how tight the internal construction is.
Best Luck!
