The problem isn't the corroded stators. The coating on the diaphragm often deteriorates over time. If you want to fix it, you'll need to recoat your diaphragms.
By the way, how can you tell that the stators are corroded without opening them up?

I checked everything on mine, and I can't really find anything wrong either. But it just won't adjust any voltages.
I now start to think that it could be the fault at PCB or the plate through holes.

I took out the VRs, and a few TRs around active battery. I couldn't find anything wrong with them, and so I put them back. One channel worked but the other didn't.
No matter how I turn the VR, the active battery voltage stays at max.
In the beginning, I had this same problem on both channels. I took out some parts to measure and put back. And somehow one channel worked. But the other channel didn't. I've sent it to a friend to help me trouble shoot now.
May I ask a question about how to measure the capacitance of an electrostatic driver? Do you measure the capacitance across one stator to the other or do you measure across one of the stators to the diaphragm?
