Technics SA-350 power supply 115V only or 115/240V automatically detected and managed?

Hi. I have this old receiver Technics SA-350.  I bought it in the USA, but now in Italy I would like to use it as second home stereo source. Is it capable to hold and manage either 115/240 volts without modification? Or I need to buy a 24o to 115 converter? Would anybody drop me two lines at wholelottasmiles at gmail dot com? Thanks. V
