Would someone kindly help me ID these two EL84/6BQ5 tubes. I received them as part of an amp purchase and the previous owner threw them in as part of the deal. Just wondering if they are decent tubes.
Distinguishing features:
Tube 1 - I believe is an Amperex. X6A inscribed at bottom. X2 just above the "x6a"
Tube 2 - UBS in diamond. Made in USA. 6 BQ5 and GJ.
