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...

Friends,

The technician is working, let's wait and see, and hear.
I'm sure he will fix it, not sure what will come out of the pre again...

Meanwhile using a Benchmark DAC as pre.

Thanks for inputs

Guys,

I learned from the tech that one of the balanced channels was toasted, the other one is fine, and since the boards are separated and equal, he carefully one was guide to fix the other.

Let's see
