I don't like to assume anything. When they fail, worry about them.
Some go on forever, it seems.
Any of the transformers that use the brown epoxy are likely to fail
at some point. It doesn't seem to matter if they are just dipped
in a thin coat of epoxy, or molded in a block of epoxy.
Somewhere during the 5000 and 7000 series tek seemed to get the EHT
transformers right. They still did some strange things that caused
failures, but at least the brown epoxy debacle was over.

Hello Chuck,
My RM565 does have the aluminum can, but so far, it has been working like a champ so far. I am assuming that this will eventually fail. I do hope that it will hold out.
But both of my 561A's and my 564 have the HV transformer out in the open. Not sealed in a plastic compartment. So, my question is, are these prone to the HV transformer disease as well? Both of my 561A's work very well so far but my 564 is in the project pile for now.
