If you plug equipment into a isolation transformer like a Tripp-lite using cheater plugs, do you still get the shock benefit?
You bet! You could receive an electrical shock if a ground fault condition were to exist under the right conditions.
(The only way I can prevent loud hum is by using cheater plugs on both my preamp and amp. Plugging them into the Tripp-lite without the cheater plugs did not work.)
What happens if you do not use the Tripp-lite and plug the audio equipment directly into the wall outlet? Still have ground loop hum?
