Full disclosure: A slight hum emanates from the left-rear side of the amp. It is a physical noise, not a sound that is amplified through the speakers. The hum is quite low and, in my setup, fades to inaudibility as one moves to the front of the amp. While playing music, even at low levels, the hum is not noticeable to me. B.M.C. suggested replacing the 2kW transformer. I purchased one from B.M.C. and traveled to their designated repair technician in Massachusetts for the switch. The hum remained, but didn't interfere with my listening.

The C2 is being offered 'as-is'. Rated 7 due to age and that slight hum. The amp is without noticeable blemishes.

Buyer pays PayPal fees (no Friends and Family), shipping via UPS Ground, and shipping insurance equal to the sale price.

Purchase includes manual, factory double-box packaging plus outer box, factory power cord, and a remote control that adjusts volume, selects inputs, mutes, and controls other B.M.C. equipment.
