The optional external power supply ($1995) accepts connections from the ’table motor and the AC inlet. (There is a power switch on the rear of the unit.) The external power supply has a rotary frequency control on the front that allows the user to precisely set the speed of the turntable. Once adjusted, there should be no need to change the setting during normal use. The motor used on the Kid Thomas is a low-torque design that helps to reduce motor vibrations that otherwise could be transferred to the platter via the drive belt.
