Hearing is believing. The
sound made when you test
substances lets you know if
you have a YES (positive) or
NO (negative). The better the
sound quality the easier it is
to hear the difference.

One Electronic Project Lab,
Cat. No. 28-265 (if you select
this method of building the circuit) is not satisfactory. However,
Cat. No. 28-262 is satisfactory, and no extra speaker is needed.
Acceptable
You may hook the circuit up to your stereo system. Make
sure you ask an expert to make the attachment. The leads
(wires) you need to do this depend on the terminals your stereo
has, but the end of the lead to the circuit should have either alli-
gator clips or mini-hooks for easy attachment. Turn the bass all
the way down, and the treble all the way up when you use it.
Headsets do not work.
Best
The Archer Mini Amplifier Speaker is inexpensive and
small (about the size of a transistor radio), making it easy to
take with you. It needs a 9 volt battery. Remove the screw at the
center back of the speaker using a Phillips screw driver to gain
access to the battery compartment. Also get an 1/8 inch phono
