Isolation transformer - high secondary voltage

[old_tv_nut]

What is the input voltage to your transformer? Hypothetically the input and output should be the same with no load, in which case your local line voltage is that high (often the case these days). A 32 inch solid state with CRT set is new enough to have a well regulated switch mode supply, and should be no problem. To run a vintage all-tube set, however, I always use a variac as well as an isolation transformer so I can reduce the AC to the rated 117 volts, which also gives the rated B+ voltage inside the set.
