Handsomely housed in a sturdy steel cabinet, with a charcoal grey front panel and polished trim, this tuner is a head-turner, and it's easy to imagine why these have become so collectible in recent years. Its classic midcentury styling matches the AA-151, as well as many other Heathkit components from the Kennedy era. This particular example is stunning, and we don't expect it to last long at this price.
