      <image:caption>In 1987, John Crane created a technical drawing of Rife's #3 Universal 1933 microscope. Due to the condition of the blueprint, we offer light and dark renditions of the drawing. The light one allows some details to show that are obscured by the dark version. The document includes a substantial list of parts on the right side.</image:caption>

      <image:caption>Schematic drawn by Dr. Oskar Gruner (Montreal, Canada) of a plasma ray device, parts of which were sent to him in 1942 by Dr. Milbank Johnson from San Diego. The device had parts added and was reassembled in Canada; it emitted only one audio frequency on a fixed carrier wave. This schematic was sent to John Crane in 1953; some notes added by Crane. Actual device was destroyed, no photos available.</image:caption>

Acquired by the U.K. Rife Research Group in early 2000s, and subsequently analyzed by Aubrey Scoon, after whom the device is named. New dating of its Eico audio frequency generator places it at 1954 or later, and almost certainly built by Verne Thompson. Thompson was a radio engineer that worked with Rife for many years.</image:caption>

      <image:caption>Device built by Verne Thompson about 1954 or shortly thereafter, and likely after the "Scoon" device above. The plasma tube shown in this photo may not be original. Like the "Scoon" device, this design used a Hartley oscillator for a fixed radio carrier frequency (currently unknown), and an Eico model 377 generator for audio sine wave frequencies. All photographs kindly provided by Dr. James Bare.</image:caption>

      <image:caption>AZ-58 model 1, September 1953. Dating of these devices follows the analysis given in Roger Blain's paper "AZ-58 Revisited" (see the Technical &amp; Patents section of the website for a copy and more details). The image of this model's interior is the only photo currently available. Most of the AZ-58s were designed by Verne Thompson for John Crane's company Allied Industries. This model used a fixed carrier frequency of 4.15 MHz produced by a Hartley oscillator. The square wave audio frequency range 50 Hz - 6 kHz was produced with use of a 3-position bandswitch, and the modulation amplitude was not adjustable. This model's components were fitted onto a relatively narrow one-level 19" chassis (case).</image:caption>

It used a variable carrier frequency of 3.1-3.3 MHz produced by a Hartley oscillator. The square wave audio frequency range 50 Hz - 6 kHz was produced with use of a 3-position bandswitch, and the modulation amplitude was not adjustable.</image:caption>

      <image:title>Plasma Ray Devices</image:title>
      <image:caption>This is the earliest model of the Eico 377 audio frequency generator, dating prior to at least 1954. It contains a "4-gang" capacitor, which does not match the "Scoon" unit.</image:caption>

      <image:caption>Closeup of the three dials used for tuning and modulation. The left bandswitch dial positions for audio frequency range are labeled A-D, different than the 1-4 markings on the corresponding "Scoon" device dial. The middle dial adjusts the audio frequency, and the right dial the modulation level.</image:caption>

      <image:caption>AZ-58 model 3, 1953. This image of the interior is the only photo currently available of this model. This model used a fixed carrier frequency of 4.15 MHz produced by a Hartley oscillator. The square wave audio frequency range 50 Hz - 6 kHz was produced with use of a 3-position bandswitch, and the modulation amplitude was not adjustable.</image:caption>

      <image:caption>"Low" device closeup of amplitude dial for adjustment of modulation depth (strength). Above it, the empty round circular location likely held an old "magic eye" for visual confirmation of the correct radio carrier frequency. The RCA magic eye was only manufactured from 1937 through about 1941, and by 1942 had fallen out of favor.</image:caption>
