• Notes

• A hi-fi stereo integrated amplifier housed in a metal case (optional wooden case) with continuous power output of  2 x 30 Watts RMS into 8 ohms or 4 ohms, with no more than 0.1% THD.  Direct Coupled OCL, phono input uses TA7136P1 low noise preamplifier IC (one per channel). With rotary controls for Volume, Balance, Bass and Treble, rotary switch for Function (Phono, Tuner, Aux) and Speakers (Off, A, B, A+B), switches for Power, Tone bypass, Loudness, Tape Monitor 1 and 2 and a jack for Headphones. On the rear panel, RCA phono sockets for input Phono, Tuner, Aux, for input/output Tape1 and Tape2, on the HG and S versions a DIN socket for Tape2 Rec/Play, terminals for two pairs of loudspeakers (A, B) and four AC outlets (except the HG version). The HG version has an IEC mains socket and separate lead.
