Neve 1272 Schematic 99%

The input and output sections of the 1272 schematic are equally critical to its sonic character. The input utilizes the Marinair LO1166 (or later St. Ives) transformer, which balances the signal and provides initial voltage gain. The output stage features the massive LO1166 gapped transformer, driven by a 2N3055 power transistor. This combination of iron and Class A electronics creates the "weight" and "harmonic saturation" associated with Neve gear. When the output transformer is driven hard, it introduces subtle low-frequency distortion and a smoothing of transients that engineers often describe as "musical" or "warm."

On the schematic, look for the 48V phantom power section. Neve 1272 Schematic
