Design Features
The input and driver stages of the C 272 are fed from a separate
Other design features include the generous power supply with a large toroidal transformer (less mechanical hum and stray magnetic fi eld) and
to low noise and low distortion. The C 272 exhibits extraordinarily low levels of distortion at all power levels and under almost any operating condition. Unlike most amplifi ers, distortion does not increase at the frequency extremes or even when presented with low impedance loads. What little distortion there is remains the same at 8 ohms or 4 ohms!
