Thanks for the information. That link includes explanations about
other tunings also. There's only that the author doesn't even claim
to know for sure that the given tuning ratios are correct for Hammond
tonewheel organs. I was wondering if anyone knew where to find the
original specifications. There is a good site for other information
at Hammond-Leslie FAQ site at

http://theatreorgans.com/hammond/faq/a-100/a-100.html

but that doesn't include anything too specific about the tonewheels
such as the bump count of a specific tonewheel or it's turning speed
related to the main shaft. Does anyone know where this kind of
information could be obtained (preferably in the net).
