Well I put my own bridge together and used a new regulator. 4700uf for smoothing and it works fine. Drops from just over 6Volts to 5.15ish when its on load so should run my American sets fine, I've got some that use DE5 triodes as well, the sets are from 1 valve up to 4, so I think I should check the load resistance as I don't really want to go with much over 5V. I guess that's why they have filament resisters 
Mark - I take your point about getting hot. I might use another box I've got - see the pics. Its a bit bigger and obviously constructed to shed heat! Not sure what it originally was though - says Cambridge instruments - DC range multiplier 3000v
All in all I think a duff regulator as mike suggested - I bought a bunch of them from china and now I don't trust them very much
