Hi,
I am wanting to make an electronic listening device and have a schematic to go by the only thing is I cannot find and listing to what the specs on the amp module are. Could any of you use your powers of deduction to come up with an idea what the specs may be?. Here's the parts list:

Parts list:
M1 Amplifier Module. (Lafayette 99C9037 or equiv.)<-
M2 9-VDC battery.
M3 Microphone
R1 20K poteniometer with spst switch.
S1 Spst switch on R1
SP1 8-ohm speaker
T1 Audio transformer (Radio Crap part 273-1380)

I think by seeing the total parts that any qualified hobbyist of electronics pro would be able to come up with what specs it needs to have. Thanks for any help you all can give. Could you also tell me what it is doing? is the amp just boosting the signal so I can hear better or so it can be recorded?. What is the transformer doing as well? transforming to what?. I know that the potentiometer is basically a volume control but what does the spst switch mean and what does it do?. Thanks again guys for all your help.

peace n love 2 ya
