I still consider his opinions the gold standard. That said, I have been purchasing the matched pairs of Psvane 12AX7-TII from Grant Fidelity. You pay a little more for Grant Fidelity supposedly picking the best pairs.

The driver can be a different brand, but the L & R must be matched tubes.

You can pick them up at real good prices. The Sylvania Baldwin green label is another one of my favorite 12AX7 type tube!
