I guess in your hurry to post, you missed the part
where John said it had a large _magnet_.

Mine was an electromagnet... which is still a magnet.
But I didn't suggest that his was. Just that magnets
are so much better now, which means efficiency is.

Also... as a filter in the power supply? Because yeah,
the one place you really want all that filtered-out
100Hz energy is in your speaker Or perhaps it was
arranged so that enough got through to the amp to
cancel it out? Crazy stuff anyhow.
