Vintage Integrated Amplifier

A ‘Made in Japan’ sweetheart from the early 70’s, here is a lovely little vintage amplifier, in excellent physical condition - tested and in full working order. Discreet design (no nasty chips or ICs) and point-to-point hand wired.

The original and rather fiddly input screw connectors have been replaced with standard 4mm speaker sockets (Banana sockets) - see picture 9.


• Power output: 13 watts per channel into 8Ω (stereo)
• Frequency response: 20Hz to 50kHz
• Total harmonic distortion: 0.5%
• Damping factor: 20
• Input sensitivity: 2.1mV (MM), 130mV (line)
• Signal to noise ratio: 65dB (MM), 75dB (line)
• Speaker load impedance: 4Ω to 16Ω
• Dimensions: 260 x 105 x 237mm
• Weight: 10lbs

The close-up pictures should tell you everything you need to know. The last picture is from the 1973 Hi-Fi Year Book.

This comes with a print-out copy of the user manual from the excellent website.
