Kenwood did a business of radio before and after doing hifi. They made some of the best FM tuners to come out of Japan. Working on their better stuff was a dream rather than a nightmare. They seemed really serious about advancing the art, quite unlike today where a tuner is a bit of an afterthought.
If you're into DXing FM signals, Kenwood had switchable IF bandwidth to improve rejection from adjacent powerful signals. As many as 5 ganged variable capacitors for tuning. Dual RF gain stages; 5 stage crystal-controlled IF amplifiers and so on. If you want one of the best FM tuners made Kenwood probably is your first choice. I hate to say it as I have serviced a good number of Marantz 10Bs which are the best of the tube tuners but I'd take a top-end Kenwood in heartbeat over a 10b despite the difference in perceived value.
