Robbie Rhodes is absolutely correct when he suggests using Ampico B
springs for Ampico A valves. Having hundreds of Ampico pianos all over
the USA by now, I occassionally get calls from some earlier ones which
were done before decent springs were available.

   "My piano sometimes won't even start to play anymore. It's like it's
losing lots of air, but you can't hear any leaks. You said it would
probably play for the next 50 years. It's only been playing for twenty,
so far. What's the trouble?"

   The answer invariably is springs. One customer got so mad at me,
deciding that all this was my fault,  he got under his piano and
removed all his valves, boxed them up, sent them to me, and told me
(this was 6 years later) to test every one of them, and that he didn't
intend to pay me a dime for what should have been done right the first
time.

   I re-labelled the box, sent them back to this presumptuous
know-it-all, and he, thinking I had done what he demanded, reinstalled
them. Voilla--- what a difference! It plays again.

   The reason are the so-called "springs" which were not springs, but
simply spanner bars used to clamp two blocks at a time. When tightened,
they merely crush the back of the blocks, which in time relieves itself
and gets loose again. Particularly in environments that have a lot of
humidty changes.

   I strongly advise everyone who owns an Ampico to change out these
iron bars to real springs. They are available from Robert Streicher,
717-559-7403, or Player Piano Company. No more loose valve blocks or
distorted and cracked blocks which can crush deeply enough to unseat
the valve itself!
