Electronic circuit : RIAA Corrector
To listen old vinyl LP's in a
correct sounding on a sassy with dynamic cartridge
you need a circuit, named RIAA corrector. This
circuit you can find in old amps, but it isn't
embedded in home cinema equipments or amplifiers can
be obtained nowadays.

semiconductors&{MJ11029-MJ11028} by ON semiconductors It is a high
fidelity audio power amplifier. Designed for demanding consumer and
pro-audio applications.
Electronic circuit : FET Audio Mixer
This simple circuit mixes two or more channels into one channel (eg. stereo
into mono). The circuit can mix as many or as few channels as you like and
consumes very little power.
Electronic circuit : Sound Level Meter
This nifty sound level meter is a perfect one chip replacement for the
standard analog meters. It is completely solid state and will never wear out.
The whole circuit is based on the LM3915 audio level IC and uses only a few
external components.
