I am 57 now and during my younger years I have been shocked by approximately 600 VDC from a charged filter capacitor in an old tube amplifier. I had just powered off the unit and had my hand on the metal chassis. My needle nose pliers hit the positive on the capacitor and the jolt was so strong my chest muscles contracted and I wound up throwing the pliers across the basement with quite a bit of force. Still have the 750 VAC transformer from that beast. On the AC side, I have been shocked by 10,000 VAC from an oil burner transformer and 15,000 VAC from a large neon sign transformer. All basically lucky situations where I was thrown clear from the source.
As for isolation transformers, when I need quick 120 VAC isolation source I take two old 12.6 VAC 2 A transformers that I have and run them back-to-back. First transformers steps down to 12.6 VAC and the second one run backwards takes the 12.6 VAC and outputs 120 VAC. Obviously for more power I would have to go with a true isolation transformer but this works in a jiffy for the low power draw circuits I play with.
