New 2A3 recommendations

Hiya

So it would seem that the time has come to replace the 2A3s on our NewAmoirs, as the original Sovteks are starting to show signs of wear.

I wondered if anyone had any recommendations for a nice replacement? We don’t rotate and it’s our only 2A3, so I’m pretty open to ideas.

Tom-s:
Two 2A3 that can handle normal 2A3 and higher operating points would be JJ 2A3-40 and EML 2A3-Solid plate.
Maybe look into those.

Suger:
Many thanks

Do you mean the Mon Amour amps?  I haven't heard them myself but the Electro-Harmonix Gold 2A3s have received good reviews.  The EMLs are viewed as excellent, though they cost quite a bit more than the EHs.

In the U.S., you can still find NOS 2A3s for around $150-$200.

I replaced the Psvane Classic 2A3-C's that came with my Stereomour II kit with matched NOS 2A3 RCA-construction black-plates (Sylvania branded), which I like a lot. Obtained from the very nice folks at Radio Electric Supply, $150 ea. The Psvane is a nice tube, but the RCA black-plates are definitely a cut above in refinement, most apparent in high-end smoothness without out any compromise in detail. This is in a new modified Stereomour II, (https://forum.bottlehead.com/index.php?topic=15167.0) that doesn't yet have the shunt regulator or DC filament supply upgrades added. I have very sensitive speakers so I hear significant the AC heater hum, and noted that the Psvains are definitely the noisier tube heater wise, but the RCA's aren't silent either. I have over a hundred hours on both tube types, and noted the Psvanes seemed to benefit much more from burn-in, especially early on, than the RCA's.
