I took apart a Wahl yesterday. (Under the advice and tutelage of DWTim. )
It started making a loud noise and he thought maybe there would be a switch (I think he said this) to control the vibration. I actually bought a set of little screw drivers to do this, as people take mine from my tool kit and then I can't find them.
Anyway, the Wahl is very interesting inside. (I'll have to do it again and post a picture.) There are really no moving parts, no "bullet" like in a regular vibrator. There is a switch to turn it on on the outside and wires and a "coil vibrator" which is copper wire wrapped many times around a spool. There was not, however, a switch of any kind to control it or alter the strength from the inside. I wasn't able to fix it. I did but a new one (with heat!) but it doesn't feel as strong as my old one. I think the old one actually got stronger as it started to break down. I LIKED IT like that, until it started with the noise.
Oh well.
