Reference 210 Vacuum tube power amplifier. Incredible tube power and sound for hard to drive speakers. In excellent condition. I HAVE BLACK AND NATURAL FRONT PANELS, you can have both for ultimate flexibility. These have had a modification - I had a quieter fan put in each amp with a switch (mounted on the back panel) for high and low. Use low for critical listening, keep it in high for regular duty. Both settings are quieter than the original fan. The fans were professionally installed at an authorized Audio Research service center.
