Tube rolling newbie- how to choose NOS tubes
I’ve purchased a xDuoo TA-30 dac/amp for my first tube rolling experience. From online reviews, I plan to tube roll in a Matched Pair of Mullard 12AU7.
Looking online, there are new reissued Mullard 12AU7, matching NOS tubes at various price points, years, features (like long plates?), and used tubes like on eBay.. This is confusing, how do I choose? Should the tubes be tested? Who should I purchase from?

B E F O R E you do anything, find out what the tubes do in the circuit:
NOS tubes can be gassy and take a while to come to life... or may never 😞 See 5963Match.png (605×341) (ielogical.com) and 5963MatchDelta.png (605×341) (ielogical.com). This is four NOS 5963 [similar to 12AU7] used as a driver stage in two amps. There are 24 possible combinations of these tubes. Each combination sounds different. And read ieLogical Rolling
