I don't know of any current production small signal tubes that better vintage tubes, and it is not just a matter of old tubes being better when driven hard. I have some old Tungsol 6sn7 roundplates that measure very weak on my tube tester. In my amp, which does not tax these tubes, they sound better than the EHs. Anyone know of current production 6sn7s that compete with Tungsol roundplates? Any competition for Telefunken ECC803S or ECC83s?
I don't know about output tubes. I really like EML 2a3 mesh-plates, but, they have to be babied (low plate voltage, low current). I have not tried vintage single-plate 2a3s, but, they make EMLs seem like a super bargain.
