Hello - I recently purchased a Classe CP-800 Stereo Pre-Amplifier from the US where the voltage rating is 120V. I live in Australia where the voltage rating is 240V. The amplifier voltage rating is confusing. On the rear right side there is a sticker that indicates that the unit is a 120V unit. On the rear left hand side there is a print (not sticker) stating the unit is capable of 100-240V. The user manual (which i downloaded from the web) specifies that "The operating voltage of your CP-800 is 100-240 V, 50/60 Hz.". I have opened the unit and there is no voltage "switch" that I can see. The unit has a detachable power cable so I can easily plug in an Australian power cable with a standard compatible three prong. - see the attachments for a visual of the left and right side labeling and power plug. Does anyone know if this unit would be safe to plug into a 240 V mains? Thankyou.
