Kenwood KT-7700 (1976–1979)
The Kenwood KT-7700 is a dedicated FM stereo tuner made between 1976 and 1979. It was sold under both the Kenwood and Trio names, depending on the market. Tuner enthusiasts speak of it with respect, but hard documentation is thin. No original manual text, service notes or period reviews have surfaced in the archive so far. What the record does show is a tuner built to a high standard, with a "Multiplicative Discriminator" circuit design and an FM-only layout. That suggests Kenwood put its engineering into the RF and detection stages instead of spreading it across AM as well.
The most telling reference comes from a Dutch hobbyist who compared it directly to the KT-8300, a model widely regarded as one of Kenwood's finest tuners of the era. The collector notes that the KT-8300 was "the shit" back in the day, but the KT-7700 is "a notch better." The same source describes the effort of bringing a Japanese-market Trio KT-7700 to the Netherlands, which suggests it was worth the trouble of an import. A separate UK listing says it was made in Japan in 1976.
One listing on a Dutch marketplace advertises the KT-7700 as an FM tuner capable of "3.5m reception". That likely means 3.5 microvolt sensitivity, though the phrasing is ambiguous. A for-sale listing on a UK aggregator priced it at £176.57, while Japanese auction bids ranged from ¥1,000 to ¥1,910. That points to modest collector demand. One less flattering listing calls it "junk * output un-possible," but that appears to be a single unit in poor condition, not a general verdict.
Beyond these fragments, the record is sparse. No detailed electrical specifications - frequency response, THD, S/N ratio, selectivity figures - have been confirmed for this model. The 0.8µV sensitivity and 110dB selectivity figures that appear in one source are attributed to the KT-8300 in the sentence structure and cannot be reliably assigned to the KT-7700. A manual exists in English (PDF format, 7.8 MB, dated 2015-06-16 on the hosting site), but its contents have not been extracted for this archive.
