  • A hi-fi FM stereo tuner with a revolving analogue dial housed in a large steel case painted in brown crackle finish with a thick aluminum front panel. With a 5 gang tuning capacitor and 5 filters. With a Tuning meter, left and right Signal/Multipath/Power Output meters (power output of the connected amplifier), rotary Tuning and Output Level controls, switches for  Hi-Blend (on/off), Muting (on/off), IF Bandwidth (Wide/Narrow), indicators for FM stereo, Wide and Narrow, rotary switches for Meter Selector (Signal and Multipath/Level/Power Out), External Attenuator (10dB/20dB/30dB), and Function (FM Mono/FM Auto/Rec Level check). On the back, a 75 ohm F type FM antenna connector, terminals for FM antennae, RCA phono sockets for Fixed and Variable Line output and for Multipath output and terminals for connection to the amplifier (input less than 30 V RMS).
