Conrad Johnson MV52

I am the original owner with the original box and owner's manual. The amplifier has no dents or scratches anywhere. The only defects are some broken plastic "flaps" that bracket the speaker cable connectors (see photos). This happened when I recently upgraded my speaker wire and the wider spade lugs were a bit to large for the space. The advantage is that it's now much easier to connect speaker wire to the amp!
The ampflier was serviced at Conrad Johnson in March of 2009 and given, at that time, a clean bill of health. It was retubed in February of 2015. Comes with one extra fuse.
"The MV52 considerably refined the circuit design of the MV50 which it superceded. In the MV52 two sections of the input tube were connected in parallel to reduce the source impedance of the voltage amplifier, eliminating the cathode follower of the MV50. Probably the most significant change introduced in the MV52 was the use of polypropylene capacitors for the main power supply filter and reservoir ­eliminating electrolytic capacitors from the main power supplies. This was the first power amplifier to offer an all polypropylene main power supply.
