Hi Bob,
I have done the same check with a number of pianos with much the same
results.  We evidently only think we are hearing the fundamental in these
low pitches.  I do not think the problem is in your "O".

Dear list,
     This Sunday at our local chapter meeting we employed an RCT to analyze
the partials in the low bass on my 1911 S & S "O".  The graph showed
absolutely no fundamental on the lowest 1 1/2 octaves.  One of our members
who works at the local Story & Clark factory suggested that there might be
a problem with the downbearing at the back side of the bass bridge.  Keep
in mind that this piano had a new board and bridges installed by New York
Piano Center 3 years ago.  I always felt the low bass was very thin
sounding.  Any ideas?

Thanks,
