Coincident Speaker Technology M300B Frankenstein MK II Mono Amp

FOR SALE:

I am selling my Coincident Speaker Technology Frankenstein 300B MKII monoblock amplifiers in excellent condition (please see photos). I purchased these in 2014 at the same time that I purchased by Coincident Statement Phono Stage (also for sale). They have been gently used in a smoke-free home and protected in an audio cabinet for as long as I have owned them.

These amps come with the original boxes and packaging and Shuguang Treasure Black Bottle 300B tubes and RCA rectifier tubes. I estimate approximately 200 hours of use. These did not come with power cords, so you will have to supply your own.

Thanks for looking! I am also listing my Coincident Statement Phono Preamplifier and will offer a discount to buyers who are interested in purchasing both the phono stage and the power amps.
