Toasted Pre

Dear all,

I live in Brazil and voltage here in São Paulo is 110 volts.
The pre that toasted (an Accuphase C2000) is 110V and was plugged to the wall in a correspondent outlet. Or, better saying, connect to a PS Audio Outlet and this to the wall. The amp I use is a Krell 2250 which is 220V and is plugged to a 220 Volts outlet without any further protection (the 220V outlet was installed by an electrician I hired since the Krell representative told to wait three week to find if they could change the voltage for me...)

Looking inside the pre there is a like a "mother board" and some four cards are vertically plugged to this, and one of them pzzzzit.

I did not test, might be that the single ended RCA outputs are working nicely.

Anyway, I think I'll find a way to convert the amp to 110V also, before more damage is done.

Best,

The preamp did not short out because the amp is fed from 220V and the preamp from 120V, jmho.

You can check the archives here on Agon and AA and find others that have or do the same now. Albert Porter for one, did at one time.

Jea48, Magfan - I concur.

I like the lightning theory.....

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
