Balancing the Brain or Cranial Electrical Stimulation
With Bob Beck's Brain Tuner & Bio-Tuner BT7
As a Cranial Electro Stimulation (CES) device, research on Beck's Brain Tuner is referred to in two recently published books: MegaBrain Power by Michael Hutchison and SuperLearning 2000 by Sheila Ostrander and Lynn Schroeder.
Over the years, suppliers of Beck's Brain Tuners apparently received feedback from individuals who found the units were instrumental in helping them overcome addictions, insomnia, depression, learning disorder and pain. Unfortunately, no company was dedicated to formally recording or collecting these testimonials.
The Bio-Tuner is an electronic relaxation system. Micro-current energy pulses appear to have a profound balancing effect on the individual and tend to produce a state of over-all relaxation and well being. The Bio-Tuner outputs a modified rectilinear waveform with over 500 frequencies in each pulse. (To see an actual Spectrum Analysis of the Bio-Tuner output, click HERE.)
The Bio-Tuner Professional Edition Model BT7 (Cranial Electro Stimulation (CES)) is a leader in electronic relaxation systems.
The BT7 Bio-Tuner outputs a modified rectilinear waveform with over 500 harmonic frequencies in each pulse. 6 different user-selectable Modes settings are available.
The BT7 offers the following advanced features:
- Quartz crystal frequency control.
- Advanced microcomputer operation. The proprietary software routine is written by SOTA to ensure consistent and reliable output.
- Built-in 20 minute digital timer.
- Custom Headset
- Very simple intuitive operation.
- A push-button switch to easily change the output to each of the 6 different modes. (Mode 1 is the same as the BT5pro.)
- Two of the modes contain the 7.83 Hz Schumann (Earth) frequency.
- Headset and Output Signal Electrical Circuit Verification Indicator
- Low battery warning light.

The BT7 is housed in an attractive custom plastic enclosure, with a built-in compartment for the 9 Volt battery. A slide-off lid allows you to change the battery easily. A Thumbwheel Switch Control Knob turns The BT7 on and off and varies the intensity of the output. The Green LED light indicates the output Mode. When the Headset is functioning correctly, the Yellow light will come ON. The Red LED light is a low battery warning light. When this Red light goes on, it's time to get a fresh battery.
The Headset simply plugs into the output jack on the end panel of the BT7.
Electrical Specifications:
- Maximum <1.5mA Peak ~40 Volts Peak-Peak into typical 4k ohm load. Minimum <~10
microamperes, 10 Volt Peak-Peak at lowest setting. Output impedance ~20k ohm.
- Modified rectilinear wave with rapid rise time (under 1uS). There are over 500 harmonic frequencies delivered in each pulse as observed on a frequency domain (not time domain) spectrum analyzer.
- Base waveform (Mode 1) 1,000 Hz Square wave (+/- 1%) pulse-modulated by 111.11 Hz (+/- 1%) Square wave. Waveforms are Microchip Quartz Crystal-Controlled for precise frequency output. There are 6 user-selectable output Modes.
- 9-Volt DC Alkaline Battery operation, useful to end voltage ~5.2 Volts. Battery drain: minimum ~9mA @ 9 Volts to maximum of 30mA with output fully loaded.
- Auto-shutoff time of 20 minutes. Controlled digitally.
- Pulses are Bi-Phasic (AC) with no DC or offset bias. Output is transformer coupled so that no direct current can appear at electrodes. The algebraic sum of positive and negative-going pulses is zero. This obviates any possibility of electrolysis, ion migration, or polarization.

- Low battery indicator. Low battery circuitry illuminates Red LED light when battery voltage falls below 5.2 Volts.
Here are the different available Mode functions for the BT7::
MODE 1-3 (550uS pulse width)
- Mode 1
1,000 Hz modulated by 111.11 Hz, 550uS Pulse Width
Output = Continuous
- Mode 2
1,000 Hz modulated by 111.11 Hz, 550uS Pulse Width, and then further modulated by 0.5Hz
Output = 1 Second ON, 1 Second OFF
- Mode 3
1,000 Hz modulated by 111.11 Hz, 550uS Pulse Width
Output = Amplitude Modulated by 7.83 Hz Schumann (Earth) Sine Wave
MODE 4-6 (220uS pulse width)
- Mode 4
1,000 Hz modulated by 111.11 Hz, 220uS Pulse Width
Output = Continuous
- Mode 5
1,000 Hz modulated by 111.11 Hz, 220uS Pulse Width, and then further modulated by 0.5Hz
Output = 1 Second ON, 1 Second OFF
- Mode 6
1,000 Hz modulated by 111.11 Hz, 220uS Pulse Width
Output = Amplitude Modulated by 7.83 Hz Schumann (Earth) Sine Wave
Other Functions
- 20 Minute Timer Elapsed: After 20 minutes have elapsed, the output is disabled, and the unit goes into standby mode.
- LOW Battery Warning: Red Light will come ON to indicate battery will soon need replacing.
- Headset and Output Signal Electrical Circuit Verification Indicator: Yellow Light will only come ON when the electrical path through the Headset is complete and functioning correctly.
