RADIONICS: Diagnosing your ailment by thumping someone else's belly

Item #209: The Reflexophone of Dr. Albert Abrams; Black wood box 10" x 6" x 4"; Phenolic top with stamped numbers; 2 jacks for connector wires. Excellent condition.


The Reflexophone was Radionics diagnosis machine and the origin of the term 'black box'.

As the first stage in his Radionics treatment, the patient supplied a sample of blood, a lock of hair, a bit of handwriting, a photograph, it didn't much matter what. The patient did not have to be present and could mail his token in from across the country. Mailing was the preferred method as there was always the danger the patient was indeed suffering from something horrible and contagious.

The Radionics Physician would put the sample in a little holder that was wired to several Reflexophones and other black boxes. The whole was connected to a pair of foot plates on which stood a healthy man, called 'the reagent'. The reagent would hold another electrode to his forehead and the Doctor would tap the reagents's belly listening for 'dull sounds' while twiddling the dials. The location of the dull sound, in combination with the dial settings at the time of the thump, resulted in the diagnosis.

When opened up the Reflexophone is revealed to be nothing but a 'resistance box'. A very badly made resistance box. The first knob selects resistances from 0 to 50 Ohms, the second from 0 to 10 ohms and the third from 0 to 2.5 ohms. The three sections are wired in series so the resistances add and appear between the two terminals.

Compare the quality with that of a Leeds & Northrup box that sold for the same $200 as the Reflexophone.
