yes - i tried it with both tesla e34l's and svetlana el34,s. i got cherry red tubes using the bias meter settings and i had no way to check plate voltage and try to bias in at a setting appropriate to and el34. i went back to 6L6's. if you're looking to smooth out the high end, look into a mod of the cap's. i had a factory mod to wima caps and it helped a lot. that and some new driver tubes really civilized it. i'm not aware of what other caps are available which could be used in place of the wima but i understand there are better caps around.
Question about Mesa Baron
I have a Baron I bought a while ago. It is a stock model--it does not have the tri-tube mod. I haven't used it for a while, but was thinking of putting it into a second system. I would like to try EL34s in it. According to the owners manual, you can run EL34s in a stock Baron. To be safe, I called Mesa. The guy I talked to there seemed surprised that you could run EL34s in a stock Baron, but after I referred him to the manual, he reluctantly agreed that you could apparently do it. He did recommend against it, though, because it wouldn't sound right--too forward and aggressive, like someone shouting at you (his words).
Anybody ever try EL34s in a stock Baron? Thanks.
