Perhaps you could try passing a small DC current through the windings. The primary of the line output transformer can be connected to a bench power supplier and adjusted for a current of 20mA. This procedure will warm up the transformer so that any moisture will be driven out of the windings.

I was planning to give that a try but surely it is the EHT overwind that is most likely to need drying out? In this transformer that is on the other limb of the transformer. Can I pass a similar current through that instead?
When I was testing different LOPT's, I was surprised at the difference in DC resistance between different overwinds. They varied from 60 ohms to 200 ohms! A much larger variation than I had expected.
