USA ONLY USA ONLY PAY PAL ONLY PAY PAL ONLY LOWER 48 STATES ONLY!!!!!!! Very rare vintage brainwave synchronizers. This is not one of the cheapie solid state current toys. The real thing used in mental institutions until made illegal. Has three variable ranges from 4 hz blink rate, to 30-100hz freq. In other words scans slow wave sleep, drowsyness, relaxed/eye closing, alert anxious/active, all way to motor functions!! Every function works perfectly. You can probably find a total description on GOOGL I would think. Tad bit dirty, couple small scrapes, bit of overspray on upper left corner, but could be cleaned. This was actually being used in a Nr. CWDX Larry K6AAW P. That is what i would pay or more if needed.
