Kenwood 700T (1975, $750, front1, front2, B&W, back, ad, detector/MPX scheme: ratio detector, diode bridge MPX, PLL generated 38k with upc33C chip) search eBay
The 700T, which predated the 600T, is a very rare 5-gang tuner whose tuning dial resembles the KR-6600/9600 receivers. According to our contributor Charles, the 700T is the only Kenwood tuner that uses an analog dial to set a digitally controlled oscillator - a very unusual system that is also used in the Pioneer F-28. We don't have much info from users of the 700T, but here are an interesting S/N test sheet and the left half and right half of the 700T schematic, thanks to our contributor Lonnie. The 700T shows up once a year or so on eBay and can sell for $350-600, with bizarre highs of $810 in 8/03 and $720 in 4/06, and a low of $305 in 4/07. But be careful: a "very unusual" tuner is not the same as a "great" one.
