If your Reproduco has 2 ranks of pipes in the piano and an octave of
pipes attached to the back of the piano, then you don't need a large
blower.  However, it does need to reach a pressure of about 6 inches
water gage.

The tubular pneumatic action needs 2 inches higher pressure than the
pipe pressure in the wind chests.  As I recall the pressure for the
pipes was about 4 inches.   My instrument was in my living room so I
wanted it much softer and so I ran it as low as the pipes would speak.

Before I had a real organ blower I used the output of an old Kirby
vacuum cleaner.  I ran that successfully for several years.  I replaced
the motor brushes once.

I will look and see if I have anything resembling a diagram.   But
it isn't so complicated that you couldn't figure it out.  Routing the
tubes is always a headache.

Let me know if you have questions.
