They probably are a pretty good sounding EL84. One of the other guys tried American Black Plates up against the Russian EL84's and he went with the Russian tubes. Of course, a lot depends on who and where they are made.
These are probably Sovtek tubes.
There are only a few current production tubes that are bigger that you don't want to use in your amp. It's all about how close the tubes are together and heat transfer.
Thanks for that, i have found some real phillips ones but they are more like £40 each, so thats why i had to ask. Bit cheeky that he is saying they are made in '67 though is it not?
