Another vote for Genalex reissue KT-77's which can be substituted for EL34's. The KT-77's sound the best of any modern EL34 type to my ears at least, and they are very rugged and relatively cheap. I also second the recommendation of Jim McShane. He is the go-to guy for modern tubes.
I grabbed some local inexpensive EH EL34 to tide me over while my NOS tubes are being tested. After the break-in, they actually surprised me and sound very good. Not going to win over this crowd probably but still interesting none the less.
if compatible with your amp, the reissue Genelex Gold Lion KT77 is stunning. Got a cryo'd matched quadset for 179 from an e____ seller. They replaced a set of Mullard EL34 xf2's and I haven't looked back.
