Many thanks to the several private and public responders to my 20-note
Deleika organ queries.  The overwhelming consensus is that I have a leak
in my bellows or chest, probably a cracked end grain or cloth slipped off
a board end, and I must find and fix that before anything else.

I timed it last night and the reservoir bellows takes only three seconds
to collapse completely after being filled, once I stop cranking with no
notes sounding.  I'd expect ten seconds or more would be normal, and one
person said to look for a whole minute!  It's time to remove the bellows
and see...

There are screws for adjusting the bleeds for best repetition, but no
adjustments I can see to regulate the flow to each pipe.  I've been
thinking of reasonably neat ways to retrofit such adjustments.

Ingmar Krause confirmed my suspicion that Deleika under-engineered
the wind supply (and also made sure I can't sell this organ to anyone
on the MMD List :-)   I already tried once, at the MBSI convention
in Chicago, to sell this organ to buy a bigger one -- preferably 31 notes
with a register or two.  (Having studied the organ and Bach, I don't
consider it an _organ_ if it doesn't have stops :-)

I'd heard that Deleika once worked for Raffin and copied his designs.
But I guess he had to make his own mistakes?

Anyway, I still enjoy the organ and usually crank through an Elvis Presley
tune or two every day (amazing what you can get cut onto a roll).  I
bought it used, so I have no idea how it played when new, although I think
the wind supply and melody pipes were a tad better when I first got it.

Thanks again,¶
