Magnet Valves for Player Pianos and Organs
By David Greene

Thanks for everyone's help with my previous posting about the
lifetime's worth of project ideas I have for our Ampico B.

I would like to make a try at a MIDI player system and several people
suggested that a "cut the tubing" inline valve system would work best.
I'm a bit overwhelmed by the number and variety of valves available.
Can anyone share their suggestions for what type/brand of valve to use?
Links to sellers would be most helpful.

I have come across some very expensive values, and some more reasonably
priced valves, but I would like to make sure I get something that not
only works well, but lasts.

I assume that such valves should be spliced in to the tubing between
the tracker bar and the stack.  Is that correct?
