Describe: differences between EL34s and 6L6s in a Nomad 55

[user 6002]

What are the differences between these two tubes when using a Nomad 55 head? What tonal differences will each make?

Thanks

EL-34's are warmer, and a little smoother. I like them in the Nomads if your able to really crank the amp up.
6L6's are fuller sounding, have a tighter bottom, and a slightly brighter top. I actually prefer the 6L6's in the Nomads. (I pretty much like 6L6's in all the Mesas I've tried).
