Default Aleph 3 with 110v->220v transformer

I got the US model of a Pass Aleph 3 amp, and in my country the outlet voltage is 220v.
I got a 110->220 volt transformer. It's rated for 300w, while the Aleph's peak consumption is said to be 250w.
Should I go with a larger transfomer? Are these known to have negative effects on sound?

Thanks in advance.

Hello roee,

You can use 110->220 transformer without any major problems.
This is exactly what I did with some of my devices that I take
with me from US.
However, I would rather use little larger transformer for the
Aleph 3 amplifier.
Around 500 VA or even higher would be much better.

Best regardsn

Default Don't see any problem

If it's rated for 300Watt and your amp only uses 250W max. then there is no problem using it.
Why spend money on a new transformer if you have one that works ?

I say test run it and if it gets too hot (the step down tranny) then get a new one. if not, use it permanently.

Look at the service manual of the Aleph 3 it's 120/240V CA compatible.

You just have to modify the wiring...
