Did you try jumpering the points indicated? Yes, the 2 boards are look slightly different but should be electrically alike.
When you say the unit sounds "sick" I assume you mean the tiny DC fan motor which blows the smoke is misbehaving? As you adjust the transformer voltage, the DC fan motor should NOT change speed and it should just be a steady "whirring."
