Hey y'all. I am looking for a decent pair of tubes for the LP. I would like to get something with good price/performance ratio. I don't need anything crazy. Just something that will be an upgrade and different sound signature than stock tubes. I am unsure if I want to venture into the maze that is eBay atm to find tubes. If anyone has a pair of good condition NOS or even new production ECC82 or similar, drop me a PM. Thanks!

I see one of my tube in LP is getting dark ever so slightly at the top and sides. Its very light dark and can be see if held against the light.
Is it common for NOS tubes?

Im going a little crazy with my 3 pair's of tubes.. you really really have to listen to the tubes for a good while before you make comments on them. I don't like the 7308's nearly as much as I thought, as some of the "wow" factor later became annoying. Im afraid to even comment on other tubes at this point for fear i'll grow to not care for them later.

I do find the stock tubes to be well extended, and rather neutral, but they have recessed mids/vocals. The 7308's for me, actually had too much midbass and did weird things to the vocal range that were not immediately obvious. Perhaps too warm. I've rolled the Amperex A-frames back in for now, and Im enjoying them, but that may change. Not sure it's fair to say that only expensive tubes sound good, it matters much what your headphone is and dac, the synergy of the whole chain, and of course your listening preferences.

My previous Schiit gear may have brainwashed me too, as it's very forward and mid-lush. (Jotunheim owner for 2 yrs prior). Which is kind of what im hearing with A-frame. Most forward and mid lush tube of the 3, perhaps at the cost of high end energy, I find the mid-bass quite agreeable as well.

So my 12AU7 to 6922 adapters came in (close to a month ship time) , they are labelled 12AX7 to E88C, im asuming that's the same thing right?

How are those of you that use these adapters preventing them from getting stuck in the LP, do you need to use a stack of a Socket saver and the adapter + tube? Im a little worried that the adapter will get stuck

Whats the favorite 12AU7 tube? I've got singles of Rca clear top, tung-sol black glass, mullard short plate, Brimar Cv4002 and JJ's, so I'd need to buy matching tubes to create pairs.

How close are the 12AU7's in voltage requirements to the 6922? I ordered my adapters before Runeights recent warning so now I wonder if I should try at all.

Same pinout, yes. I think the 12AX7 has higher amplification factor, but in term of adapters - same as 12AU7.

I’ve got a pair of Amperex PQs in my LP right now. Can anyone speak to the differences I’d encounter by rolling in the Mullard 6201s?

I don’t want to go crazy tube rolling but having the stock tubes, Amperexs and one more seems like a good place to be. The Mullards intrigue me given the praise in this thread.

Anyone else getting good results, with 6922's? Still digging the Brimar CV2492, but got the itch to roll. . .I am looking for some Holland D getters, but they are scarce, at the moment.

I have seen that, with some of my tubes, and especially the Philips, Holland tubes, but nothing to worry about, as far as I know.
