Hi, Rx8man,
I don't know about those tubes, no experience. I have heard that some older sovteks are much better than the current kind used in a lot of componenets. If they are not expensive, it is always worth a roll.
I like the Amperexes best. Orange Globe Amperex 6dj8's (the kind with a splatter shield, some variants don't have splatter shields) have a very nice earthy midrange that I really like combined with sweet highs. Orange Globes are excellent in that transition zone from the lower midrange to bass in dynamic material. Amperex white labels (bugle boy types) have very spacious imaging and nice highs, but they tend to have less overall body than the orange globes. White Label A getters and orange label A getter Amperexes are about half way between the standard orange label and the white labels in sound, a nice mix.. Mullards that I have heard have nice midrange, but not as sweet on the highs as the Amperex tubes.
Ediswan tubes are very clear and balanced, but are rare and expensive, they are more like Siemens and Telefunken types.
