What tube is the hampered? What does it fit? Sounds like I must have one

I was running the orange logo, exactly the same from the side presented (green) with a crystal like logo on the other side. Also USA made

By all accounts a great sounding tube.
Around $100 - $150 per tube from decent sources.

The 770 do indeed use different pads, 990 and 880 are stated to use the same 990 pads. However, I had a pleasure to own all 3 models (all in Pro) and the 880 pads were actually the perfect marriage of 770 and 990. The sound signature was indeed of the 990, however they are as firm (i.e. not flattening under clamp pressure) as 770 at least the factory fitted ones (quite frankly they also look the same as 770s, unlike 990 ones). Have a photo of the 3 somewhere specifically illustrating the pads, will post if can find it. The worst are the 770 drummer edition pleather ones, but the phones themselves are also highly specific.

Try Dekoni pads, they have a whole range for the DT series.
They do come with a price (you looking at around 50USD plus delivery and tax if applicable) but I only heard good things about them, still on the to do list for me to try them out.

Off-topic:
Regarding the DT990 Pro, they absolutely need a valve, no other way and the warmer the better.
I was running mine on Aune T1 Se (tube integrated as part of the DAC circuit with a solid state amp section) with an Amperex Jan 7308/Reflector 6H23p-EB. Unfortunately dropped Amperex not that long ago so currently sitting on a Reflector until can source replacement Amperex. To my taste Amperex is THE single perfect valve for DT990 Pro from what I tried. Having said this - I would suggest to run a backup valve for routine use (hence the Reflector). Reason - Amperex pushes the brightness, sound-stage, clarity, amount of detail et cetera to pretty much borderline infinity (this is especially true for sound-stage) which creates an insane holography and density which in term may be a little overwhelming if you are not in the right mindset and mood at the time. While providing an absolutely GORGEOUS result this combo can get a little tiring for a laid-back sort of "background" listening. Reflector is much less bright and aggressive while maintaining a very nice sound-stage, imaging and detailing. But my suggestion is if you go down that route, try it out on various valves if you have an opportunity to decide for yourself which one is more suitable, but still do yourself a favor and do get at least a test run on Amprex, you will not get disappointed.  ;)

The only model I haven't owned is the DT880 - are you saying that the DT880 pads are NOT exactly the same pad as the DT990? Even though Beyer themselves state that it is?

The DT990 Pro absolutely becomes a different beast on tubes - I found it sounded spectacularly good with 1980's 6992EH.

From Beyer:

EDT990 is for DT880 and 990 only, they cannot be used on DT770 variants.

As previously stated, I would only replace pads with the stock ones - why try fix what ain't broke?

Experimenting ;)
For me personally getting Dekoni is purely in the name of science and fun. Well and I do want something just a little more spacious than the stock ones ;)

Re Amperex: Yup, looking at 100 pounds for a NOS from UK right now, well plus shipping and tax. Unless can source something locally.

Re Pads: Well this is the thing, I 100% accept the fact that Beyer does state the 990 Pro and 880 Pro are running the same pads. But as I stated they both look and feel different. Sound signature wise and isolation wise once again I would say they sit right there between the 770s and 990s. Signature wise very close to 990s, visually very close to 770s. This, of course, talking about the factory fitted pads.

The 2 phones on the right both appear to have DT770 Velour (EDT770V) pads although the bottom set, which I think are DT990s, appear to be somewhat squashed out of shape.  The DT 880s on the left have EDT990V pads.
