i think you are right about the very likely lack of a new internal transformer. Seems like that would be far more expensive of a change.
so, where do I begin? Pop off the top and take some photos, and show the community for advice?
does the 50hz 60hz change have an effect here? Portugal is on 50hz, we’re on 60hz. Does the Rewiring of the transformer take this into account or solve this problem?
i am a tinkerer by nature, and I have some DIY skills. That said, I am no electronics engineer! If I am going to attempt this, I’ll need to have a good plan/procedure in place. Any advice to how I might proceed and what the tools and skills necessary may include?
are we talking soldering? Or perhaps just some sort of detachable wiring terminator that holds the wire to the points on the transformer?
lastly, is there any way to know for sure, before I risk disaster, that the new wiring scheme is 100% correct? As I am not familiar with Power supply transformers, I am not aware of there is a common standard that is obvious to an engineer.
It is not worth risking my gear if there is a chance of catastrophic failure. That said, if it is possible to see/envision the correct wiring scheme will total confidence, I think I am game to do the conversion myself.
last but not least, I have a medium size step up transformer here in the USA. I suppose I could test the component at 220v to see if it works, and still be on the correct side of the Atlantic to get it fixed at the factory if I fail!
Thanks!
