Best EL34 reissue?

A couple other thoughts in addition to my recommendation of the Gold Lion KT-77s. From the recommendations you've received it should be obvious that most members have experience with at most a few of the available reissues and likely none of them used them with the same components you have.

There has been quite a bit of discussion of El34s and KT77s in the Tube Forum at audioasylum.com. Do a search there or post the same question you've posted here.

As mentioned above, there are a number of reputable dealers who do have experience comparing most of the available tubes, that's how they make a living. Send an email or call them, tell them what you're looking for and ask their advice. I've had great experience with Jim McShane and there are a number of others.

A great alternative to consider is the reissue Genelex Gold Lion KT-77. With most amps it is a drop-in replacement for EL34s with the characteristics that people love about EL34s. Do a search on audioasylum.com for some informed opinions.

I've used mostly vintage EL34s over the last ten years in a couple of amps, original Teslas, RFT/Siemens and others, and the Gold Lion KT-77s are right up there with the best of them, with the big advantage of being able to source them tested and matched from great dealers like Jim McShane and knowing they're new production.

Of course, which tube you prefer depends on the rest of your system and whether you like your music sparkly, mellow or somewhere in between. Also depends on what you consider affordable, around $200 for a quad seems to be the entry point for really good sound in an EL34.

Yes, the blue glass is just for the look, which has always seemed crazy to me.

The clear tubes with the orange glow are part of the fun of having a tube amp. One of my friends calls it "the electronic fireplace."
