Amp specs
All I can tell you is Class AB 120 watts, Class A 30 watts, I have a service manual which the specs are listed in Japanese so I can only guess at what they are. I do not have a manual but an electronic version of the service manual. The amp features are: 2 phono inputs, MC setting and MM with 27K, 47K, 100K settings. Seperate tone controls both channels. Eq subsonic filter. Tone controls can be switched on, off or straight DC operation. Tape monitors, headphone jack. Loudness +8dB, +4dB or off. I do not have the original box but have a shipping container for it. It weighs about 35 lbs unboxed. Hope that helps.
