2A3 Recommendations & NOS Noise

Our George Wright Mono 3.5 amps come stock with Sovtek 2A3's, which are not a bad tube at all IMO. However, I prefer the more open sound of the NOS tubes, the 1940's RCA's in particular. Problem is, I've sent back two pairs of them because they were too loud. They either buzz or burble at levels that are audible over the music. I now have the opportunity to get a pair of Sylvania's or early Tungsol's, but I'm concerned that those could be noisy as well. They all have been coming from a reputable tube source, by the way.

Has anyone heard the EH Gold Grid 2A3 tubes? I've always found the EH tubes to be a bit dry sounding, but hear good things about their 2A3. They are said to be a big improvement over the Sovtek's. Any opinions?

Thank you,
Howard
