  • Notes

  • A hi-fi stereo integrated amplifier housed in a black metal case with continuous power output of 2 x 70 watts into 8 ohms (2 x 80 watts DIN into 8 ohms). With Bass and Treble tone controls, push button switches for Direct, Phono MM/MC, Speakers (A,B,On/Off), Loudness, Subsonic filter and a jack for headphones. On the back, RCA phono sockets for input PHONO, TUNER, CD, and LINE, for input/output TAPE1/DAT, TAPE2, TAPE3/ADAPTOR and terminals for 2 pairs of loudspeakers (A, B).
