Good day, I have an amp Matchless Independence is originally from USA and works with 110V. As I understand electronica. I take it apart to look at the power transformer and see if a connection is available for 220v primary winding.
I did not find what I expected but analyzing what I see draw some conclusions I would like you to correct me.

above is the schematic of the transformer. I think that if I connect the coils in series then would have the same but with a primary transformer 220v.

My only fear is what happens to the current? I think it will be fine because the voltage needed to bend half amperage.

If I test my idea without charge and a lamp series with the transformer is safe for the transformer this test? there is no risk of burning it?

thanks
Alejo
