Hi Lyle,

Wikipedia seems to think that an "air amplifier" is a kind of
pneumatic piloted valve/fluid amplifier or pneumatic equivalent of a
transistor - it has two input streams (a high pressure, high volume
one and a low pressure, low volume one) and the low pressure one can
control the flow of the high pressure one. I don't see how that
relates to what you describe. Do you have an actual brand name where I
could get more info about the kind of air amplifiers you used?
