The Heathkit AA-100 Deluxe Stereo Amplifier stands heads and shoulders in value above any other stereo amplifier in the kit industry. Packed full of exciting features, this high-fidelity rated 50 watt amplifier outperforms units selling for twice its price. It's a mere $84.95 in kit form, that's just $1.70 a watt for two 25-watt channels of distortion-free power to handle every amplifying task in your stereo system.

The five stereo inputs can be utilized to the advantage of your individual taste and system components ... there's a stereo magnetic phono input, a pair of tuner inputs for AM and FM, a pair of tape inputs and two pairs of auxiliary inputs. A separate monophonic magentic phonograph input is also available. The input layout is further enhanced by the fact that tape playback heads can be accepted directly without external preamplification or equalization.

In addition to three different stereo speaker impedances, the AA-100 has a "mixed-channel" speaker output that can be used for stereo "center fill-in" or for monophonic sound in other rooms. The cathode follower outputs for tape recorders insure true sound reproduction without high frequency loss, regardless of the distance between the amplifier and the recorder.

The many controls of the Heathkit AA-100 speak clearly of it's versatility and capability in any situation. Included are preamplifier input level controls, power amplifier input level controls, hum controls, "mode" selector, speaker phase reversal switch, baance and separation controls, ganged volume controls and separate concentric bass and treble tone controls to put you in complete command of every function with assurance of peak performance.

While the electronics of the AA-100 are enough to prove this stereo amplifier the best buy on the market today, the wonder styling features of this beauty make it an even greater value. The luggage tan vinyl-clad steel cabinet looks and feels like real leather, but is practically indestructible because of its mar, scratch and stain-resistant qualities. The fabulous AA-100 is the "stereo-twin" of the famous Heathkit AJ-30 Stereo AM/FM Tuner ... they look alike, and will fit in any room decor in your home.


Equipment Notes:

The unit does not power up but it has the Vacuum Tubes still intact.  I don't know what is wrong with it and don't have the time or desire to fix it.
