Teardown: Magstim 200 TMS Transcranial Magnetic Stimulator Base Unit

In this video i disassemble a Magstim 200, this is a TMS device manufactured in the late 1980s. Production began in the mid 1980s and ran through until at least 1999.

TMS is a medical technique to stimulate the brain and nerves throughout the body using a closely coupled induction coil placed on the head that is energized with a short duration high voltage/high current pulse. The magnetic field from the coil induces small currents into the brain or nerves through the skull and skin.

The Magstim Company was founded from research performed at Sheffield University during the early and middle 1980s.

I recently purchased two used Magstim 200 base units for teardown. One appears to be working and dates from the late 1990s, the other is broken and dates from the late 1980s. It's the broken one i teardown in this video.
