Vaguely remembered retro tech

[sawyl]

Somehow over lunch, I got on to the subject of pneumatically amplified gramophones, despite being a big vague on the details. I couldn't remember what the things were called but I vaguely remembered something about the involvement of one of the Short Brothers and something to do with turbines. Well, it turns out that player things were called Auxetophones, the Short was Horace Short and the turbine connection was Sir Charles Parsons.
