Ever wonder how op-amps work? Have you heard the term, but are unsure
of how to use them? This kit, based on the LM1458 Dual
Op-Amp, fills you in on op-amp basics and provides a
working preamp, capable of amplifying microphone-level
signals to the point where they can drive a power amp (such
as the EBAA-1 or AP-1W), Featuring two high-gain stages, each with
an adjustable output level. The stages can be connected
together to provide one high-gain preamp, or used separately for stereo.
Power requirement; 5 to 10v DC, P C Board size: 2.25" x 2.75"
