<html> <body> John, I too saw this in an old Lyon & Healy grand that we rebuilt a few years back.  Interesting that we both found them in LH grands.   I assumed at the time they were some type of heating/dehumidification system, but it was just an assumption.  We find interesting heating units inside old Hammond organs also.
