Voltage Conversion-Ayre Amplifiers.

Hi,
I have a plan to buy Ayre Pre-Power amplifier from Audiogon. MRP of HIFI is very very high in our place and so buying new is beyond my imagination. Please let me know whether the voltage could be easily converted from 110V to 230V by a good Technician. Please help me. Your earlier reply will be very much appreciated. Thanks.
