The Shugang cheapy 2A3b with white or black base for well less than $100 a pair are not bad. Based on my positive experience with EH 300B, I suspect the EH 2A3 might be quite a good value as well. (I should pick up a pair and try them). KR stuff lacks availability, is poorly constructed, and is overpriced. Craig lost money on the KR PX-4s because he just ate it on the returns. The story is after Kron died, his wife took over and didn't give a crap. This is just a story though. EML is good, probably the best of modern tubes, but expensive. I like the EML 2A3 and 300B mesh. The Psvane replica WE275 is good and sounds most similar to NOS 2A3s. The Psvane WR2A3 is very bloomy. My preference on the DNA Stratus has been the EML 2A3 Mesh. Sounds the most neutral with best bass control. If your NOS Miniwatts sound good, just stick with those. They if already work fine, they should last a long time.
