Toasted Pre

I have a 220V amplifier (Krell 2250) connected to a 110V pre (Acuphase C2000) and after an year of faithful service the right balanced output from the pre toasted!

I’ve attached some photos of the board so you can see the problem I have here.

It seems I should not have mixed 220V with 110V in the same system.

The technician says it can fixed with parts he can find here but I thought of asking the more experienced...

Best,

DO NOT plug the pre back in.....until fixed properly. That board is TOAST.
And, since I see that chip is cracked in half (!!) I'll have to say it was Really Really hot before failure.

Since you had the proper voltages to each piece, I don't think that was the problem.

I don't believe the board can be salvaged.
