Hi Rob you were lucky, if you were measuring anything but voltage and current with the mains switched on to the set.
If that was a mistake and no harm was done that's fine but you need to get into a drill/routine when ascertaining the state of any mains powerd receiver etc, if not sure about anything always unplug from the mains and have a re think.
Reading ohms on the mains in etc with a meter that doesn't show any sign of stress etc could give you a false sense of security ie: my meter hasn't gone puff so the radio must not be plugged into the mains, you make a return path via your hands while poking around and ouch or worse.
If a radio of unknown quantity appears dead then the first check is to check continuity with a meter with the mains plug unplugged.
Good luck.
Lawrence.
