Where to put best tubes in AR Ph3-SE

I have a PH3SE, (and a PH3). The V1 and V2 positions are the right and left channel tubes. Both of these need to be matched and of lowest possible noise. The V3 is a cathode follower and just needs to be of good quality.

I have always used (3) matched, tested, low noise tubes for all three positions, but I'm anal...

thanks for the anwers. Exactly what I needed to know.

FWIW :

I bought a PH3-SE after hearing so many good things about it. When I got it setup I was never really all that happy with it. I tried to read up on tube rolling suggestions for the PH3 but I had trouble finding much written about it. I did get a piece of local advice to try gold pin, JJ 6922’s. I swapped out the tired set of Electro-Harmonix 6922's with the JJ tubes. I had planned on the eventual NOS set of gold pin Amperex PQ's but I wanted a stop gap before shelling out for a quad of NOS PQ's. In short, I was nothing short of amazed, for a relatively small investment I got a huge improvement. If I was looking for a "third tube" I might be tempted to replace the cathode follower with the JJ and put the big bucks in the PQ's. I plan on a backup set of JJ’s just in case. It’s a good reference point for me. Are there any other suggestions for the best possible tube combo in the PH3-SE? I am always interested in hearing of peoples experiences with this phono pre. In spite of being less than impressed with the PH3 initially, I now think it’s great combination for my basic vinyl setup. I am even considering a SUT from “Bob’s Devices” and a new low output Denon cart. Matched with the step up tranny, I figure my cartridge selection will be greatly expanded and the PH3 will have a long happy life in my system.

I ended up using NOS American Amperex tubes with a modern Gold Lion remake as the cathode follower, and am very pleased. Big improvement over EH's used previously.
