Remember them, Don? I even HAVE a few left in my house for special circuits to the furnace and water pump. Disclosure: both my house and camp are over 100 years old...

Some would argue that replacing the burned-out fuse isn't a permanent solution; it's only temporary until the fire starts.

I'm not wading into this grounding question except to say I ran an electronics store in the mid 70s, and we kept wondering why all the audio equipment kept failing. We had the electric circuits tested and the entire wall of AC outlets were improperly grounded, setting up a floating ground through anything (or anyone) who 'connected' a chassis to ground. The current was just enough to blow equipment and give your teeth a little chatter, too.

Thanks for the trick about testing the remote with an AM radio.
