A 19th-century synthesizer that broadcast music over telephone lines. You'd pay to listen to electronic telephone concerts. The power needed was so great that the music signal would crosstalk to nearby phone lines.

It only ran for a handful of years. As this got started, radio was becoming more widespread.

Aw! That's an instrument I've not thought of for some time! I did a whole presentation on this creature at Uni, and made a javascript version that might still work, at least on desktop! :)
