For what it's worth, I finally ordered tubes for my v6. Based on a lot of input from here, plus the lure of the 10% off Tung-Sol sale at Tube Depot, here's what I ordered.
Mullard 12AX7 for v1 - Hear lots of good things about these, plus I like the one in my old Super Champ. Seems a good tube for a Brit style amp.
Tung-Sol 12AX7 for v2 - Based on some input from Coco in another thread (quoted above). Sale is nice too!
JJ 12AX7 for V3 - Don't care too much about the PI, so the JJ seems reasonable. Cheaper than a T-S or Mullard. Plus, Coco uses JJ or T-S in the i/p anyway.
JJ EL84 for v4 and v5 - I've liked JJs before. Plus, two out of three recommended them in this very thread. There was an E-H recommendation, but they are said to be bright. I don't need any extra brightness out of an EL84.
JJ EZ81/6CA4 for v6 - It's a rectifier. Plus, Coco uses them in Trinity amps. So why not?
Tung-Spol 6V6 for v7 and v8 - These seem to be the ones everyone recommends. I've used them in my Super Champ too - plus the sale!
Thanks to everyone that chimed in. I've been very pokey beginning this build. Drooled over all the parts and perused the instrucions the other day. Meant to do way more over vacation, but there was always other family/kids/puppies type junk to do. Should get a nice start over the next few days before work on Monday. Of course, I took Tuesday off to watch the Buckeyes in the Sugar Bowl. May get some amp time that morning too!
