McIntosh MC275 Replica 735,000yen(including-tax, around the 2007 time)

Description
 
Stereo power amplifier which pursued a low distortion, efficient, and wide band-ization without spoiling the originality of MC275 put on the market in 1961.

The unity couple circuitry original with a mac and the bifilar-wound output transformer are employed.

KT88 is adopted as an output stage.

4ohms/8ohm/16ohm has adopted the gilding termination as the speaker termination and imbalanced input terminal which became independent, respectively.
Moreover, the gilding contact is adopted also as a tube socket.

The stainless steel chassis of specular surface finish is adopted as a chassis.

Unbalance / balance changeover switch, and the stereo / monophonic changeover switch are carried.
