Sometimes, they get Shuguang to make them STR's (Special Tube Requests) to their specs/design, but it's far more common to see the same couple of diferent Chinese 12AX7's just be rebranded.

What's funny is Shuguang actually make a have a copy of the Russian Sovtek WB.

Is that what STR was?

Are TAD EL34B-STR Selected's considered good? Any way to tell WHAT the special request entailed? Got 4 of em in a cheapie marshall off CL

Looks like they're visually the same tube as the Ruby EL34B-STR?

TAD tubes are usually well-regarded. I guess they're good if they've been reliable and sound good to you. Only way to know is to try other stuff as well.
