Back when the Earth was young, the old Maranz PianoCorder system had a power
supply that was a first class space heater. I've seen those things kill
pianos outright in a year. The current (sorry) PianoDisc power supply seems
to have a much lower BTU output rating, and I haven't seen a big problem
with them, but I can't help but think that a localized heat source like this
isn't good for a soundboard. I'd like to see a fan that blows down, and out,
and runs continuously. Just my under informed opinion.
