Afraid I don't have a clip to offer yet, but I just put a set of SED EL-34's in my V and I will not be going back anytime soon to 6L6's. Not quite sure what it is, sounds like it has a bit more gain and REALLY smoothed out the high frequencies. I had some SED 6L6's in it, and they are great too, just sounds allot warmer to my ears. Try a set, you can use them as backups if you prefer the 6L6's. You don't have to get the SED's, other brands are somewhat cheaper.
