[CAUT] Piano Life Saver Systems and Disklavier

[Andrew Anderson]

I had this same discussion with pianodisc.  They did not voice any  
concerns regarding use of a DC piano life saver system.  When I  
installed the PianoDisc system on two Sauters that already had PLSS on  
them I did look at proximity of components.  I also utilized an  
undercover and ran it over top of the power supply (which vents to the  
side not the top) to isolate its heat contribution from the piano.

If you are looking for stability, an undercover and string-cover will  
go a long ways.  Adding a dehumidifier system only should be  
compatible with Yamaha's concerns.  The full system does work better.

YMMV
