Man you’re speaking like a kindred soul here - I feel almost exactly the same way, and yeah, I also went way too far. On the plus side, my tube needs for life are easily filled. On the downside, it’s far too hard to liquidate these collections without a lot of give-aways and/or accepting pennies on the dollar. I'm just not into recouping funds 100 bucks at a time, for the effort involved here. So eventually, someone inherits the problem.
These days I spend less time tube rolling, because most vintage small tubes sound really good anyways, and your hearing just adapts to their nuances over time. If I want to change sonic flavors in a much more meaningful way, it’s easier to swap a cartridge or SUT (or components, or speakers).
Versus signal tubes, power tubes actually yield a more meaningful delta to shaping the sound IMO, but they’re mostly new (not vintage) and it’s pretty quick to hone in on which is the "right" choice for an amp. With small tubes you can easily get into a back-and-forth never ending hell trying to figure out which you actually like better.
