Audio Amplifier

<< < (6/6)

staticshock:
The circuit consists of a differential input with transformer coupling and then goes through a network of resistors and capacitors. The differential input then goes through a TLE2144 Op-Amp to become one signal that gets amplified by another TLE2144. (For now, only one output is needed for testing.)

Transformer coupling has always been used so it was preferred for consistency as well as impedance matching of 600 \$\Omega\$.

I've read that for audio circuits, polystyrene and polypropylene capacitors are recommended(???)
