AM Tuner AJ-20

• anderer Name: Heath Company

Heathkit AJ-20. For high-fidelity AM reception at a budget price, you can't beat the Heathkit AJ-20. Self powered, this little giant packs three tuned stages for best sensitivity and a full wave voltage doubler detector for lowest distortion. The "fidelity" selector switch gives you a choice of maximum selectivity or maximum fidelity. One of the two outputs is variable level cathode follower type for direct driving of power amplifiers, regardless of cable length; the other output is "fixed" for use with preamplifiers. A built-in rod antenna and terminals for an external
antenna are included. Flywheel tuning makes station selection quick and the edge-lighted slide-rule dial is easy to read.
