I've not read any threads discussing the use of a tube PREAMP into a Vetta. That just seems very strange to me to preamp the preamp section of a Vetta amp. What does make much more sense (and I've tried this successfully myself a long time ago) would be to hook the line outputs into a tube POWER AMP.
I use my Marshall 9100 dual rack mount 50w per side tube power amp that offered Class A/B and Class A modes into a Marshall 1960A stereo cabinet. I even wrote to the tech department and others @ Line 6 saying how terrific it would be to have an optional tube power section in the amp or as an option. nothing was ever done with the Vetta, but amazingly - Bogner comes along and does the exact thing I described with a Spider amp. Go figure?
Maybe this might help you.
here's where i read it at http://line6.com/support/message/59527#59527
i know that the vetta ii sounds better with the armin mod, but i want it to sound as close as it can to the real thing. i know i can't get the true tube sound, but maybe a tube pre-amp (or power amp) will help. the thing is, i need a cheap one.

I agree with MerlinFL suggestion to look into using a tube power amp more so than a tube preamp. The tough thing is that a beneficial tube pre amp or power amp is not cheap by any means. Using a cheap or low end tube pre amp or power amp is more likely to just add hiss and noise to your signal, so be careful what you buy.
