SC10 Discrete Op-Amp
The SC10 is an updated, "slightly improved" version of the Quad-Eight AM10 amplifier used in that company's legendary Coronado, Pacifica and Ventura consoles. This all-discrete 12 transistor design retains the original's topology and compensation scheme, but adds improved current sources and employs more modern transistors throughout. The SC10 is best used in circuits with medium to high source impedance and with mic input transformers with 1:8 or higher turns ratios.
