Micro-Tech 1200 Amplifier Service Manual

Voltage Conversion

The 120 Volt 60 Hz version, sold in the United States, is not voltage selectable. It does not have voltage selection boards. This version is to be used only with 120 Volts and only with 60Hz.

All other versions of the Micro Tech 1200 use voltage selection boards. The following chart indicates which jumpers are used for different voltages. Note that the fuses and transmotor may need to be changed to accommodate different voltages. Versions with the voltage selection boards may be used at 50 or 60 Hz.
