Motora Turbine Suction Pump in Duo-Art
By Paul Camps

Hi,  I've encountered several Steck Duo-Arts over the years with
Motoras.  I have a friend that had two Stecks, with a Motoras in
each of them.  Despite restoration of the player mechanism the
Motora ran hot and scarcely generated much above 22" wg vacuum.

Compared to the four-lobe mechanical pumps usually fitted they
were a waste of space.  Perhaps they were just a poor man's option;
no doubt someone will comment on that speculation.

I actually made from new a four-lobe pump which I fitted in place of
one of the Motoras.  As far as I know it still survives to this day.

So, Niels, if you can find a mechanical pump, put one in.  It's not
original, but what the heck, at least it's less likely to catch fire
and that's got to be good for health and safety.
