Original old stereo vintage ad for HARMAN-KARDON INC.  Main office was located in Westbury, Long Island, NY. Citation I and II Kit, preamp control center, stereophonic power amplifier shown.  We don't pack an engineer into each kit but the the engineering built into each one is so precise that the unit constructed in the home will be the equal of the factory-produced instrument.  Build the very best. This unique old one page 1960 high fidelity stereo equipment component trade magazine advertisement would display beautifully matted and framed.  It would make a nice accompaniment to your vintage stereo.
