OVERVIEW

The K-160 monaural power amplifiers represent the culmination of a decade of research that followed Koch's celebrated K-70 valve amplifier.

FEATURES

Entirely solid-state, operating in pure Class A at 100% into any impedance, the K-160 employs only N-type transistors, eliminating crossover distortion entirely, and runs zero negative feedback throughout. Its reactor-based power supply provides a static, constant DC current feed to the output stage regardless of program demands, eliminating the modulated supply noise that compromises conventional designs. Output: 150 watts into 8 ohms, 230 watts into 4 ohms. Distortion: 0.0009% at 5 watts. Signal-to-noise: 125.5dB at 100 watts. Each K-160 weighs 45 kilograms and is assembled, tested, and personally approved by Koch.
