Yamaha Concert Grand Ampico Piano
By Craig Brougher

To any who might now or in the future wish to adapt a concert grand
to an Ampico player, while I don't have parts for sale, I have done
this and can give you help with the problems you will encounter --
particularly dynamics and longevity.  Both points are crucial when you
are talking "concert stage."

It isn't too difficult to do.  The Ampico is supremely suited for the
concert grand, which has several times more power than the largest baby
grands have.  So the dynamic steps all remain in the same proportion
relative to each other, regardless how much power each successive step
must have.  But the pump, which has been sized for a 6' grand, must be
doubled in capacity to power this piano, and the spill system and
amplifier must be readjusted for the piano's increased dynamic range.

So when you find a pump, it should be one with metal connecting arms,
or you will have to have a new crank system machined for it (best

There are also many other details that will make for a much better
playing, far longer-lasting instrument.
