Folks, have to confess that I ordered a 110V version of the 709A, even though I'm living in a country with a 220V 50Hz supply.
I opened the unit to have a look at the transformer, and I saw that the circuit board that probably implements the single phase triac
is labelled 110/220V.
Question is: does anyone know if I have a hope of modifying this PCB (assuming I could get it out) to be happy with 220V? I would be thrilled and willing to put in the work, because the alternative is dropping 200-300USD for a high-rating step down transformer, or stubbornly spending 100 USD to build one, which probably won't be as good.
I have also submitted a question to Sunko itself but I don't know how responsive they are.
sheepishly,
Barry
