Model Q Relaxometer

The Model Q Relaxometer has a loudspeaker, and a socket for standard light-weight stereo heaphones, with a Volume control and a Frequency adjustment to set the tone for the particular user. In contrast to the Model S, the Model Q also has a meter so you can see changes too, and a socket for suitable external apparatus.
