Are all GZ34's born equal?

[catch29]

Well Guys ( if I'm allowed to say that!). I'm glad it's thrown up so much debate. On my other working pair of MA-12's is a Mullard and a Bugera (Behringer), I can't tell the difference, they're both fine. I might try some vintage old/new russkies if I can't find some Bugera's. I shall dream of a Mullard.
