Aric Audio Super 2A3 owners - favorite tubes?


Hello all,

I've been enjoying my new set of Aric Audio amps (the Super 6SN7 linestage + Super 2A3 amp) and have been playing around with different tubes. I am curious what tubes anyone who owns either of these prefers.

I swapped from the stock 5U4GB to some NOS RCA 5U4Gs, but not sure if there's anything better out there that owners may prefer rectifier-wise. Asking Aric, he said GB or G works fine, but beyond that didn't offer any other alternatives as far as compatible tube options.

For my 2A3 tubes, I have a set of NOS Svetlana SV-2A3 (2C4C) and EML 2a3-S Meshplates and prefer the EMLs. The Svetlanas sound nice - they are a little more 'warm' sounding to me - but they lack the detail and wide holographic soundstage that the EMLs produce.

For the 6SN7 tubes on both the pre-amp and the amplifier (3 total), I've tried Sylvania JAN 6SN7GT VT-231 2 Hole Bad Boy, Black Plates an d NOS RCA JAN 5692 6SN7 (red base) tubes and prefer the Sylvania's by a mile. Swapping from the Sylvanias to the RCAs, bass thinned out quite a bit. Detail was great, and mid/highs were nice, but the Sylvanias are overall much nicer.

What have you tried and liked / tried and kept?

Has anyone used the KR 54UG or Sophia Electric 54UG? Bonus if you've used them and compared with EML Mesh 54UG or NOS RCA 54UGs.

NOS 5U4G RCA is not something special. I like Ken-Ran 5u4G. But Linlai 5u4g are on the same level and very cheap. I had a U52 GEC/Brimar brown base. It was really great, better than other stuff I had but it is crazy expensive now. I bought it when it was already used, and after 3 years it died. But to buy one today is too expensive.

Mmcgill829,

If I were you, I'd reach out to Brent Jessee to discuss your needs. He has a ton of hard to find 2A3, 6SN7, 5u4G tubes; and has great insights. He does not give away his tubes, but he does stand behind them with a warranty
