PARTS SOURCES FOR THE MRA

Joel and Norm now report that stranded wire seems to be required in
order to see the strange effects.

(22 " gauge, read update 9 !)


The transducer used in the Keelynet device was obtained from a surplus
source local to Texas.  We're trying to track down more of them.
They apparently came from an industrial plastic welder.

A Lead Zirconate Titanate piezo transducer can be had from H&R corp, but
its dimensions are: 2" dia x 0.1" thick, not the same as the original
Keelynet device.  It has a 45KHz resonance.  Will it work?  Dunno.  They
have several hundred in stock.

H&R also carries numerous ceramic magnets, but it's unknown whether or not
any are close enough to Norm's original that they will work.  They offer
one large ceramic magnet, 4 x 3 x 1", and have only about 50 in stock.
This magnet has its poles on the flat magnet face, and has TWO poles on
each face.

At least two kinds of ceramic magnet exist: Barium ferrite and Strontium
ferrite.  It is not known whether both types work in this device.
