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?

+ whatever on Brent Jessee.

@kennyc  here is the link to his website, if you click on the specific tube type you are interested in a page will come up with impressions on different brands and equivalent tube models

 

I haven't used Vintage Tube Services , but as noted by another member he gets good reviews. Another option is TubeDepot

"To void risk of being skimmed, buy current tubes."

Buy from credible vendors and you don't have to worry about it
