The original "Radiation Analyzer" consisted of a chamber to hold a sample of material, a glass prism to refract the "eloptic" emanations coming from it, and a copper wire probe on a rotating armature to adjust the angle formed by the prism and the probe. Supposedly, "eloptic" emanations are refracted by the prism at different angles depending on the material. The detected "eloptic" signals were fed to a three-stage vacuum tube RF amplifier and conducted to a flat touch plate surrounded by a copper wire bifilar coil. By stroking the touch plate an operator could supposedly feel a sensation of "tingling" or "stickiness" when the "eloptic" energy was detected. As such, a human nervous system is considered to be necessary to operate a Hieronymus Machine.
