Having said all that, once either finds another station, the other will tune right into to it, and usually not much difference, other than the quality of the 'soundstage,' imaging, or whatever that depth quality is called. The KT-8007 also adds a front-panel headphone jack, which the 600T does not have. The L-01T is an extremely rare FM-only tuner that is seldom offered for sale in the U.S. Our panelist Jim was lucky to have a chance to play with one: "The inside of the L-01T is amazing, with two potted transformers and 3 full wave bridge rectifiers for 3 totally separate regulated supplies. Without exception, this guy excels in every realm that for my purposes is important: 1- Within literally five minutes it was obvious that its sensitivity elevated it to within the top four tuners I own; 2- Its selectivity in its unmodified and unaligned state is magnificent; 3- Though I've neither the test equipment nor the expertise to verify the operation of the multiplex demodulator or the audio section, my ears tell me that if they're not perfect, they're mighty damned close. I've checked the schematics of the KT-5020 and the KT-6040, and I see many differences. The KT-8007 was Kenwood's top-of-the-line unit produced just after the KT-8005 and right before the KT-8300. Before modification, Peter ranks the KT-1100SD just below the Kenwood KT-8300, but after modification it improves a lot in both audio quality and DX capability and will, in some respects, outperform an unmodified KT-917. But our panelist Bob adds, "The 8005 and 8007 seem a lot better [when in typical 'as found' condition] than the earlier KT-7000 and KT-7001, which seem to need parts/repair to work well, rather than just an alignment." There is just something more going on, more like the band is in the room somewhat at various places or centered at different times. Kenwood KT-7550 (1978, photo, service manual, schematic, PC board) search eBay This circuit is how Kenwood reports such low THDs. Sold only in Europe when new, the KT-9900 is identical to the KT-8300 in every way except for the 9900's worldwide voltage capability and the color of its front panel, which is usually "gun-metal" (a metallic medium gray) but we've seen it rarely in bronze. Except for LED lamps, they are as-found, likely stock tuners. Our panelist Ray "had to play some DX games with the KT-8300 vs. the Pioneer TX-9800 and Optonica ST-7405. There is also a button labeled Active Reception that switches between letting the user manually select the IF and RF settings or letting the tuner automatically select those settings." Our panelist David "A" adds, "I learned that the L-01T was actually made in two distinctly different versions. The KT-8005 uses two 4-stage filters, early ceramic type, in small metal boxes labeled "MuRata Ceramic Filter" on the top. KT-7500s with DIY audio section and power supply mods as described on our DIY Mods page have sold for $170 to over $300. It may not be the worst idea to install a fuse holder and fuse in other models when you're working on one anyway. However, our panelist Jim calls it "a masterpiece" that he found comparable to the McIntosh MR 78 for DXing, with better sound than the Mac. Kenwood KT-880D (1987, $269, service manual, schematic, audio section) search eBay This was a big change point for Kenwood, as the KT-9XG still had the Pulse Count Detector." When Active Reception is engaged, the tuner makes its own decisions for the Direct/Distance and IF Band settings. Our panelist Eric agrees that the L-02T is a dream machine in all respects from a DXing standpoint. Kenwood KT-880D (1987, $269, service manual, schematic, audio section) search eBay David Rich offers this analysis of the scarce KT-3300D: "Pot adjustments subtract these internally generated distortion components from the composite using trim pots (separate pots for stereo and mono). The L-1000T is seldom seen on eBay and can sell for anywhere from $325-600 or more. Also on the back panel are RCA variable outputs and an output level control, multipath outputs (horizontal and vertical) for an oscilloscope, and a 75-ohm antenna jack. I've checked the schematics of the KT-5020 and the KT-6040, and I see many differences. The IF stages are Wide/Narrow selectable with two 250 kHz GDT ceramic filters in Wide and two 220 kHz CFs put between them in Narrow. Stereo Decode Thresholds The unit is big and heavy, and its footprint is a bit larger than the 600T's. It has the classic Kenwood silver-faced styling (the "gun-metal" gray-faced version of the KT-8300 is the KT-9900), a powerful front end with a 6-gang tuning capacitor, and the potential for top-quality sound after an alignment. The 3-gang KT-4007 is the baby brother of the KT-8007 and KT-6007. In a nutshell, the KT-8007 is more reliable, and is similar in many ways inside to the KT-8300, except that the 8007 still has the single IF path. Kenwood KT-7000 (1970, $250, front, back) search eBay The little brother of the top-of-the-line KT-8007 is a good-sounding tuner in its own right. I have upgraded several of them and have gotten excellent results. The L-02T is seldom seen on eBay-U.S. and usually sells for $2,000-3,000, but one with poor photos sold for just $1,000 in 8/09. Lots of fun for a $5 garage sale item." The treble isn't hot or irritating but does have some extra sibilance due to all those old electrolytics in the signal path (if I hadn't heard the difference after putting in new caps in other tuners, I wouldn't see it as a problem). Ray also entered the KT-8300 in a DX shootout with the TX-9800, Denon TU-800 and Technics ST-S8, with the results summarized in our writeup for the latter tuner. 's website.The KT-8300 usually sells for $150-250 on eBay, but around $120 and over $300 are both possible. The KT-8007 has a 5-gang front end, 2 4-stage ceramic filters (equivalent to 4 modern 3-pin filters), and a discrete output stage that combine to make one of the best-sounding tuners around. The rare L-1000T is a solidly built FM-only digital tuner that was Kenwood's attempt to recapture its '70s-early '80s glory. Of course we're not trying to imply that the KT-5020 is the equal of a L-02T, but I think the KT-5020 offers great performance for the price." The little brother of the KT-8005, the KT-6005 uses all discrete circuitry and some say it sounds great. With 4 gangs and 3 280 kHz (wide) filters in stock form, the KT-7300 has the potential to be a decent tuner for DXing (but not as good as a modified KT-7500) when tuned up and modified with narrow filters. "I only see 4 filters but the block diagram shows them as 'either/or' in filter selection. When I tested them for adjacent-channel performance, the TX-9800 and KT-8300 could both ignore the adjacent, but the ST-7405 had lots of interfering hash." I've been inside this tuner twice. See the KT-3050 entry above for more of Greg's KT-5020 findings. Like the L-07TII, the L-07T has a 7-gang tuning capacitor and is also very sensitive and quite selective even in stock form (spec'd at 100 dB alternate channel selectivity in Narrow). The little brother of the KT-8005, the KT-6005 uses all discrete circuitry and some say it sounds great. Kenwood KT-917 (1979, $1,000, photo, schematic, detector/MPX scheme: pulse count detector, discrete CMOS switch driven with slimed pulses (no charge injection cancellation) generated by analog means, MPX PLL generated 38k with HA11223 chip) search eBay Being a audiophile rather than a DXer, I am more inclined to purchase based on sonics. This creates one additional step for each new tuned station for those wanting to surf stereo stations via the Manual tuned mode. The bottom is fiberboard with plastic or aluminum sides. Bass was there, but not with the definition, punch and dynamics of the Accuphase T-109V. Kenwood KT-8300 (1976, $380, photo, inside, owner's manual, service manual, audio section 1, audio section 2, RF section) search eBay Compared to the KT-5020, the MR 78 was very two-dimensional and 'transistory' sounding on live Public Radio broadcasts. Without exception, this guy excels in every realm that for my purposes is important: 1- Within literally five minutes it was obvious that its sensitivity elevated it to within the top four tuners I own; 2- Its selectivity in its unmodified and unaligned state is magnificent; 3- Though I've neither the test equipment nor the expertise to verify the operation of the multiplex demodulator or the audio section, my ears tell me that if they're not perfect, they're mighty damned close. The L-02T is seldom seen on eBay-U.S. and usually sells for $2,000-3,000, but one with poor photos sold for just $1,000 in 8/09. It really is a reality check: it doesn't have 'stock' (chip) IF, MPX and output stages which, I feel, can generate a certain amount of 'sameness' among tuners. The sound is pretty good, stock, with better-than-average bass and a good midrange, but more than necessary sibilance in the highs." There is a pivoting arm for the dial pointer wires to move freely. Another contributor says he owned one around 1995: "One of the most unique tuners I have ever seen or used. Kenwood L-02T (1982, $3,000/orig $1,800, photo1, photo2, inside, front AGC, Hi-Fi News review, detector/MPX scheme: active IF, PLL detector, first order sample and hold, MPX PLL generated 38k with TR7040 chip) search eBay KT-3050 - 2nd -48 dB, 3rd KT-5020 - 2nd -64 dB, 3rd Stereo Separation I noticed that with the AFC on there seems to be somewhat more bass. It's useful to be able to detune slightly when a desired weak station is adjacent to a strong local. The KT-6007 historically sold for $30-70, but since 2013 sale prices have drifted up for unknown reasons to the $75-115 range (and one even went for $150 in 1/16). -Editor] Kenwood KT-6050 (front, left, right, back, inside) search eBay We're not sure what the difference is between the KT-9X and KT-9XG -- we thought the "G" in the model number meant gold front panel, but some KT-9XGs have silver faces. The audio stage uses four 8-legged op-amps (4564 DA) supported by four 16-legged op-amps (MB84066B). Our contributor Stephen says, "I finally got around to listening to a recent eBay purchase, a stock KT-7500. The L-1000T has an RF amp bypass (like the Onkyo T-9090) to reduce front end IP3 but at the cost of sensitivity. The KT-8007 has a 5-gang front end, 2 4-stage ceramic filters (equivalent to 4 modern 3-pin filters), and a discrete output stage that combine to make one of the best-sounding tuners around. However, in one of the worst eBay purchases we've seen, two ignorant bidders ran up the price of one KT-5000 from $33 to $168 in 4/15. Peter notes that there is also a tuner called the KT-1100D, "which looks almost like the KT-1100SD, but with AM added and with smaller buttons. The KT-815 has 5 gangs and 4 filters, with the main differences from the KT-615 being the extra gang and an output level knob on the 815's front panel. Kenwood KT-9900 (1977 or 1978, photo) search eBay Sanyo out." 's website.The KT-8300 usually sells for $150-250 on eBay, but around $120 and over $300 are both possible. KT-5020 -.05 dB Draco Afterwards I bought a KT-9900, Onkyo T-4650 and T-4711, Revox A76, Creek T40, Hitachi FT-5500 MKII, Sony ST-J60, Denon TU-580RD, and Yamaha TX-900. It also has scope output jacks on the back panel. Any filter modification should probably be done by a pro because the L-07TII contains two Murata "Surface Acoustic Filters," specially designed by Kenwood (top row in photo), for the wide IF bandwidth setting and 3 older-style 4-pin 280 kHz ceramic filters which have 4 stages each (the center one in this photo was replaced as part of a mod) for narrow mode. The L-01T is an extremely rare FM-only tuner that is seldom offered for sale in the U.S. Our panelist Jim was lucky to have a chance to play with one: "The inside of the L-01T is amazing, with two potted transformers and 3 full wave bridge rectifiers for 3 totally separate regulated supplies. At that time the output follows the composite. Our panelist Jim tried to enter a KT-1000 in a Shootout but it failed its physical: "I had problems with this tuner from the start. Post-mod, it is comparable to a modified KT-8300 for DX performance, but maybe not quite as sensitive as the 600T. The KT-1100 is fairly common on eBay-Germany but very rare on eBay-U.S., where it usually sells for $120 or more. Our contributor János had one and after alignment but without any mods, it had "still worse RF capabilities (a bit worse sensitivity and clearly worse selectivity, although the Revox has only a single IF) than a KT-6040 or the Revox A76." With its pulse-count detector, 1 kHz THD measured 0.03% in wide and 0.5% with the modified narrow filter. Kenwood KT-7020 (1990, photo, German info sheet) search eBay
