My samson servo 120 amplifier says that it runs on both 100V and 220, but it blows fuses. How to run on 220V?

Question

I thought i could just plug it in here and that it would work, but the fuses blow. {I did change them to the proper amps] There is no switch visible. I want to know how to use this amplifier here. It was fine in the USA. How to change this amp so that it can run on 220 V, like it says on the back?

Answer 1

You have just burned it. There should be switch somewhere. You can't plug it to 220V directly.

Autovolt appliances are normally marked 100~240V. Not 100V and 220V.
