MV125 Vacuum Tube Power Amplifier

Introduced July 1991

The MV125 vacuum tube power amplifier superseded the MV100. It was designed for audiophiles who had larger than average power requirements or less efficient speaker systems. The MV125 delivered 125 watts per channel using two pair of 6550 output tubes per channel. This amp debuted conrad-johnson's transpectral output transformer design - a specifications for intricately interleaved windings that theoretically is capable of unlimited bandwidth, and in fact increased small signal bandwidth by several-fold. This design was later implemented in the Premier Eight, Eleven, and Twelve power amplifiers. Also in common with these later models, the MV125 used polypropylene capacitors for the main power supply reservoir.
