valve experts - 6sn7 suggestions?

I just picked up a pair of VAC PA160 mkII monoblocks. They utilize 6sn7's in the input and driver stages. I have a quad of what appear to be NOS GE's. I was wondering if anyone has experience with the GE's. Also, what 6sn7's (or variants thereof) are you running? Thanks for your comments. Erik

Thanks for all the input. I can't wait to start experimenting with all the possible combinations. The PA160 mkII's have so many variables. Tweaker city, baby. Erik

Erik;
A real learning experience about the 6sn7's will start by paying a visit to Andy at V.T.S. (Vintage Tube Services)
He has a nice web page and is the authority when it comes to tubes of all sorts. He will soon be writing a book on tubes, and it should be one of the best around. He will straighten out any confusion about the voltage ratings and what you might need. I tried numerous Ken-Rads, Tung-Sols and Sylvanias from him, and it was an enlightening experience.
He has a great return policy, and will give you plenty of time to try out various ones. The Sylvanias have much lower
microphonics than the Ken-Rads and Tung-Sols, and are less "colored sounding" with the VAC amps. Happy tweaking!

Bigshutterbug (great handle),
Thanks for the lead. A valve return policy? Amazing. I have a buddy who has the same VAC's that I do. We are both benefiting from this thread. Again, thanks everyone.
