Looking at the circuit diagram it follows the classic op-amp with a long-tailed pair of NPN transistors driving a PNP gain stage and finally a complimentary emitter follower as an output buffer.

Op amps. Often the first thing that many learn about when beginning the journey into analog electronics, they’re used in countless ways in an overwhelmingly large array of circuits. When we ...

The Rattler MkII arrives with an all-new new circuit design and custom op-amp, as well as switchable ... it offers three knobs of tone-shaping via Level, Gain, and Tone, but with the addition ...
