Hello Tre'

I remember that in the early 2000's a lot of the discussions of tube cathode heating were about the differences between regulated and non, as well as differences between voltage regulated and current regulated.

If a regulator is used the supply that feeds it might have a lot less impact on the sound.

Rod Coleman's design idea (as I understand it) of putting high impedances at both ends of the cathode in a DHT does seem to have merit as his regulator's do make for good results. I guess that might line up with your use of the choke on the output of your supply. I don't remember who it was back then but there was another Asylum member who talked about his supplies having a choke in series with each end of the filament to good effect.
