It would be nice to add a tube regulator to eliminate the need for a 60lb external regulator.
I have not seen reference to that 6080 circuit in any of the 21CT55 service literature publicly available.
How much is your supply varying? Do you have aluminum house wiring?

If your supply varies so much that you need a regulating transformer, maybe you should contact your electricity utility.
