What is the sound characteristic of OpAmp LT1364CN8?
I don't remember anymore but I did find my answers on Little Dot website. The site has an Question and Answer section that covers general questions about tube rolling and opamps.

What is the sound characteristic of OpAmp LT1364CN8?
Received my LD I+ today. It came so fast it beat all the tubes/op amps I ordered. So far 2.5 hours on the stock tubes and pretty impressed with it. Next I'll be trying GE 6DT6A which I found at a local store.
Great dealing with David and incredibly fast getting it, less than 5 business days!

I thought the RCA and Tung-Sol 6DT6A sounded better than the GE's, but I never compared them to the stock tubes and would be interested to hear your impressions.
Cheers
Has anyone rolled Op Amp AD8397?
AD8397 is used as Op Amp in Hifiman HM-901.
Has anyone tried to mix the different brand/maker but same family tubes ?
For example, is it ok to mix one WE 408A tube and one GE 408A tube in LDI+?
It is perfectly safe to do this. However, the WE and GE sound different. And so the tonality of the R and L channels will sound more different than normal.... But again, it is perfectly safe.
What about if I were mixed one Sylvania 408A and one Philips 408A? Some headfiers claimed both are equivalent.
Any comment?

At the local store that was the only tubes I could find, so didn't have much of a choice unfortunately. As for comparing the GE 6DT6A to stock tubes, it takes me a little too long to switch the jumpers so I can't do a very good A/B test on them. Also found Westinghouse 6DT6A so I will compare them to the GE 6DT6A since that's just a quick tube swap.
I am not sure, but I don't think Westinghouse made 6DT6's. So I believe that the Westinghouse tubes were manufactured elsewhere and Westinghouse simply painted their name on them. You might want to take a close look. If they have the same construction as your GE's, then probably GE made them. If they look different, then perhaps RCA or another company made them.
Good question.
#1 GE 6HM5 and #2 Westinghouse 6DT6A have identical white letters with the tube model and dots below (hard to see in pic).
#3 and #4 are both marked GE 6DT6A but #3 made in Japan, #4 made in Canada. None of the 6DT6A look very similar in construction..
