KENWOOD KT-815 PULSE-COUNT TUNER IN BEAUTIFUL CONDITION Picture(s) and Description:

 219832805998273230 KENWOOD KT 815 PULSE COUNT TUNER IN BEAUTIFUL CONDITION

I call this “gift grade” because there’s not a scratch or blemish on the front panel, and the case is spotless except for a small “dot” the size of the head of a pin on the right side toward the back. It might even rub out. These pictures don’t do this set justice. And it works perfectly, with unreal clarity. It almost sounds digital. This tuner probably has less than 300 hours of actual use, but in any event, it can’t be as much as 500. I bought this in October of 1982 when I lived up on top of a big hill near Oglebay Park, between Wheeling WV and Pittsburgh Pa. This was the top-rated DX’ing tuner back then, and everyone had huge antenna arrays because there was no cable TV out in the country, and satellite radio wasn’t even invented. I had a tall stack of antennas and even a UHF dish on my roof, with a serious antenna rotor system. I even had an AC-powered Blonder-Tongue head-end amplifier in a watertight enclosure up on the antenna tower. The reason I bought this tuner can be seen in four of the auction photos: Besides the usual fixed and variable audio outputs, it has VERTICAL and HORIZONTAL “multipath” outputs so I was able to hook up an OSCILLOSCOPE and perfectly align my antennas by viewing the waveform from the detector section. The scope I used back then, an EICO 460, can be seen in one of the photos. Anyway, this created a pattern on the scope screen, which went to a flat line once you got the antennas aimed directly at the station. If it was oval, or similar to a Lissajous pattern, then it meant it was receiving a “multipath” signal from the radio station: one directly, and one that was bouncing off a mountain or something. Sometimes this was unavoidable, but with this tuner I was able to find the best (and least distorted) position. Once this was determined, I marked the azimuth setting for the rotor on a chart. I sometimes applied this concept to TV stations that were in line with known radio stations, although TV multipath is easy to see in a TV picture, so I mainly used this tuner for radio. But for everyday listening, I used a JVC receiver because it had a built-in graphic equalizer, and I was recording the radio music to create cassettes for my car, and I needed to plump-up the sound because back then car stereos had weak bass. After I finished my chart, I boxed this tuner back up and stored it at my parent’s house, where it remained in a main floor closet for 15 years. After I moved out to the DC area, I picked it up and used it again to record some 6-hour jazz and rock specials off-air, and also, the AM section is so amazing I was able to listen to WVU football games from over 300 miles away on WWVA-AM with just a set of rabbit ears, even though I was now living at sea level. This tuner’s FM sensitivity actually beats the more expensive Kenwood KT-917 (1.8 uV versus 1.9 uV), and the AM section’s 9 uV sensitivity easily beats almost any other tuner’s AM section. But WVU football got “big” and the games got moved to TV, and also I got into CD’s instead of FM radio and cassettes. So this baby went back into the box until now. To show how the scope output works, I hooked up a more modern scope and used a set of rabbit ears to produce the three other scope photos, but on my Tek scope the trace is vertical. I was using rabbit ears and the station was much closer than they were when I lived in the mountains. But you can still see how the system works. This will come with the original box and owner’s manual, but the box is ratty looking now so I’ll put it inside a new UPS box. If the winning bidder doesn’t want the original box, just let me know. This will be very, very carefully packaged. Everything works like new, the dial glides from one end to the other like it’s riding on melting butter, and it gets full signal strength on Washington DC stations from my basement clubroom, again with just rabbit ears. I hate to let it go but I never use it, and my son is into iPods and MP3’s. Complete with the original owner's manual. The complete specs can be found in the last scan. Compare them to modern tuners and decide for yourself!On Dec-09-10 at 07:36:54 PST, seller added the following information: If this is to be a Christmas present for someone, and the winning bidder would like expedited shipping, just let me know before you pay and I'll figure out the extra cost. But I can't imagine that standard UPS Ground won't get it to you in time, unless you live on the west coast. I plan to take it directly to the UPS main shipping hub on Joh Avenue in Baltimore, and I'll get it up there quickly. While surfing the web for articles about this tuner, I came across one called "The AIG Tuner Project" (2007). Apparently some audio labs like to buy this tuner and "soup it up" because it has a lot of unlocked potential - sort of like some specialty auto shops do with muscle cars. Anyway, here's an interesting quote from that article "“The soundstage is large (not compressed) and spatial characteristics are excellent (even more so than the KT-917). I could easily discern individual instruments and their placement in the soundstage. The stereo separation is an incredible 55 dB and signal-to-noise ratio is an extremely quiet 80 dB in stereo. This tuner really does live up to these specs. "
