Thanks Scott, but if it were only a difference of 200Hz at the top
end, I wouldn't have mentioned it.  Using a tuning meter, with the
knobs at "10", the one I built has a top frequency equivalent to G#
-1, but the one I bought built only goes up to A# -4 (a difference of
about three octaves).  One the low end, without having to bring in a
geologist or building some kind of timer, around "4" on the knobs,
the one I built will cycle once, while the one I bought used will
cycle ten times.  Perhaps one of us made a construction error??
Based on what you say, 320's shouldn't vary that much.   Any idea
where I should look??
