Hi All,  In my research, I have read about the possibility of pedal
solenoids overheating and binding up.  Also the striker solenoids and
power supply do put out a good deal of heat.

I can see where all this heat might not be good for a piano that
is closed up and under continuous use, like a lounge.  What I am
wondering, has anyone ever heard of a properly installed system
actually causing a fire in a piano?

Because my Pianocorder Obensetzer is fairly tightly packed into its
Dynavoice case, I have added a cooling fan to the side of the case
near the power supply to draw off hot air from the components, more to
protect the components from breaking down due to excessive heat than
any concern about fire.

Thanks,
