I am selling my B&K ST140 amplifier. The B&K ST-140 is a highly regarded vintage solid-state stereo power amplifier from the late 1980s, known for its "tube-like" musicality, reliability, and affordable audiophile performance. Designed by Steve Keiser, it delivers roughly 105 watts per channel into 8 ohms and is noted for its smooth, sweet sound, especially in the midrange.

I just had it serviced and it is working as it should. I have owned several of these and as claimed they are sweet "tubey" sounding compared to other solid state amps. I can hook it up and demo it for you.
