Heathkit AJ-21 High Fidelity tube AM Tuner

I forgot I had this thing until I was rearranging my shelves of equipment. It's from the early '60s, and has extremely heavy (for its size) solid metal construction, designed to look like a car radio of the time. It's just a tuner, not a complete radio, so I ran it through the tape input of my Kenwood receiver/amp. It has a bandwidth switch, but you can't really hear the difference due to the limited frequency response of my camcorder's microphone. You can leave it in wide bandwidth mode while tuning, but I switch it back to narrow mode for better selectivity, to pick up more stations. The tuner is all original, including the tubes and capacitors, and works fine, but it could probably use a realignment because the sensitivity drops off noticeably above 1200 kHz (at least using the included loopstick antenna), and the whistle notch filter that is supposed to be centered at 10 kHz actually has the notch at 10.7 kHz so it's not really effective at silencing adjacent carrier whistles. Back when I was recording this video in 2008, both 1250 WMTR and 1450 WCTC used the same "Good Time Oldies" satellite music format; that's why you hear the same song playing on both stations.
