Signal tube versus power tube, sound impact?
Amp manufacturers know that people are going to roll tubes anyway - it's part of the charm -  so why not let them do that for themselves. That is also what I think, @bolong  .  +1.

JJ preamp tubes - repeated problems
Popped the top on the preamp and the top of the tube was completely burned out.  When I went to pull the tube the glass completely disintegrated.  I had a pair of 6550 (output) tubes (in an amp) redplate for way longer than I ever should have l...
