A winding can impregnated with epoxy without being potted in it. I restored my early 453 by rewinding, and it wasn't potted. See topic and photo album titled "453 HV Transformer Rewind".

The reason I don't think that the transformer epoxy is going bad is because the transformer is not potted at all. I can see the windings. My understanding is that later transformers were potted. I have the early style supply with the vacuum tubes for the 12kV high voltage doubler.
