Where to put best tubes in AR Ph3-SE

Of the three tubes in a ph3-se, are they all equally important? Which spot should I put my best one or two tubes?

I'd try to go with some (matched) premium tubes in those positions first.

I got three Amperex Bugle Boys and Andy sent instructions to put the best graded tube in V1 the second best in V2 and the third tube(which was graded slightly lower than V1 and V2) to be used in V3. When I called him to order he knew all about the phono stage and the tubes it used. I took his advice and enjoyed the results very much. Hope this helps. Thank you Jim

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...
