I haven't really heard anyone with this basic mod to their mesa... so if you do, tell us about it!
I didn't have EL34s, but I went with JJ 6V6s tubes in my recto. I wouldn't limit yourself solely to the idea of EL's. That thing sounded so huge, warm, and raw once I made the switch to the 6V6s. It was so organic sounding that I thought that granola was going to shoot out the speaker cabs while foliage sprouted out of it. It was pure hormone-free, free range beef! It still retained the heaviness, it just lost some of the fizz and hi-fi-ness(?) of the standard recto sound. It isn't that I didn't like my recto before, but it was a whole 'nother beast with the new tubes. I loved it. Too bad I had to sell it...
6V6, not 6L6?
What EL34 are you using PUH?
Yup. JJ6V6's. Euro tubes has a little description, here. Scroll down just a bit to get full info on the 6V6 swap.
It was a pretty rockin' set up. One of my favorite amp tones to date.
The Single Rec's that are switchable from 6L6 to EL34 mode can also use pairs of 6V6's, KT77's, KT66's and KT88's for a lot a tonal variations. The bias does not have to be modded and made adjustable if the proper grades of tubes are used.
