OK, great! I have been trying to find exactly what you have or something similar for a while for a decent price. I see old RCA WP-25A units on Ebay that aren't too high priced, but they aren't variable. Usually anything that is variable and isolates from the line is not cheap. I guess I could buy one of the basic 1 to 1 ratio transformers I see and use it in conjunction with my Variac to save some money.

Am I to isolate the equipment being tested or the test equipment, or both?
