Product Summary

The STK401-140 is a two-channel AF power amplifier. It allows users to construct a product line of amplifiers with differing power output capacities using the same PCB design y simply changing the hybrid IC used. The STK401-140 supports 3 and 6Ω drive to handle the recent trend toward lower impedance speakers.
