• Notes
• The Crosley Harko No. X (10) incorporates one stage of Crosley Tuned Radio Frequency Amplification before the detector. The Model X consists of one stage of tuned RF, detector and two stages of audio frequency amplification. Crosley: "It has ample volume, even on distant stations, for any purpose. With a good grade of headphones or a horn, music from stations several hundred miles away can be heard all over the house." The Model X sold for $55 without accessories or $112.50 complete with tubes, batteries, aerial and phones. This first version has pointer knobs and first version of rheostats, but never had an overhanging lid - as shows "Radio News" in September 1922, page 406. In the ad in "Radio News" July 1922, page 87 it is named "Harko No. X - Tuner, detector and amplifier in one cabinet." but no price or picture is given.
