There's a picture of the md2 circuit board on my site:

MD2 is a dog to work on. AT the right hand end of the circuit (this is old type), a few tiny transistors that tend to explode on the board. New version board has larger transistor patched in with wires.

Mechanically, yes, simple. But have you seen the electronics? There is a

MD2 is no dumb electric motor.
