Good job with the cleaning.

Did you desolder the other ICs that are not directly corroded? Because underneath, in most cases, there is also corrosion that is not a problem yet but could be in the future.
Then I rewired all the corroded parts on my board, put it all back together, and started an initial smoke test. Then nothing happened, and all the voltage was lost in the white ceramic resistor used for voltage preselection. So the transformer had too low resistance. First, I searched the voltage selection circuit for a problem because that's often where the problem is. But then I connected the transformer directly to an AC source, and it was drawing too much power without anything connected.
I will post X-rays this afternoon.
