Who actually makes the different groove tubes labled tubes? I know they don't actually MAKE any tubes themselves, just relable/test and match other peoples stuff. So who makes the different tubes they use?
According to the Torres Enginering site the groove tubes 6L6S is made by JJ/Tesla. Thats the only one I've been able to find out.(I dunno if thats true or not though)
Anybody know any others?
