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,

I'm not sure I understand. Was the line voltage 110v or 220v? Were you using the correct step up/down transformer on the power line to which ever component didn't match the line voltage?

As long as both the pre and power amp each saw their specified voltages you shouldn't have a problem.

Please clarify.
