How to change voltage settings in a Classe CA-2300


My ca-2300 power amp keep blinking in a protection mode after a repair.
The problem disappear when it is connected to a PS Audio P5 power plant and not directly to the AC mains.
Thank you.

Hi Elisabeth,
Thank you for your answer.
Also sorry for reverting to you so late (I have been traveling abroad).
Actually I live in Brazil. There, the PS Audio power plant P5 (which was lent to me in order to test the amp) is 3 times more expensive than in the US. Would you recommend a generic product to get rid of such DC offset? For instance would an isolating transformer be a good answer?
Again thank you.
