                              BHK amp shown in silver, also available in black

The BHK Signature features a zero-loss vacuum tube input stage coupled to a high bias deferentially balanced MOSFET output. This amplifier has few rivals at any price and produces 250 watts per channel into 8 ohms. The BHK Signature power amplifier culminates one man’s life long quest for perfection in power amplification. Bascom H. King’s magnum opus combines a vacuum tube input with a powerful MOSFET output capable of either 250/500 watts per channel in the Stereo 250, or 300/600 watts in the mighty Mono 300.  The BHK Signature Series amplifiers can drive any loudspeaker to musical perfection and is the second most important element in your music reproduction chain behind the loudspeaker itself.
