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?

As a tube newbie myself, I’m more than happy to pay up a bit for a reputable tube expert with a reasonable return policy to point me in the right direction and who will likely save me considerable time and $$$ from buying either the wrong or bad tubes.  I’d just make sure to have a price point in mind going in and communicate that upfront because this can get silly expensive, especially if you don’t know yet what your doing or what tubes are really worth.  Great advice here that I’ll definitely use myself.
