Thanks Jim,
Any problem with the cathodes flaking? As I mentioned in my post I run 505V rail in my Macs. It is also have a rather stiff power supply. I had the misfortune of having a couple of Teslovak KT88S tubes fail in rather spectacular fashion when the cathodes flaked and shorted the grids. Also I had problems with SED 6550C tubes not working well in my amps as the plates had a bit of glow to them.
