This is the Softone Model 4 phono stage, very well designed and made in Japan. It has ample gain for MC cartridges and muting function. It uses relays for switching inputs and MC cartridges are routed to a pair of step up transformers. Its stock tubes are a pair of Sovtek 12AX7LPS. I bought it used from a man from California and need a voltage step down transformer as it is 120V version, but its not a problem as the power consumption is a low 15W. The seller has already swapped the stock tubes with a pair of NOS Mullard M8137 (CV4004) which sounded excellent. The gain is a high 69dB and there is no noise and hum.
High quality inputs and components used throughout. Already a good value at the online price of USD650, I bought it for USD400.
