MHDT Orchid TUBE ROLLING

213cobra... Interesting post. I own the new MHDT Orchid and am currently using a Western Electric 396a. Do you know if a 5670/396a to 6922/6DJ8 tube socket adapter requires any circuit alterations in the Orchid? Petrhaps a question for MHDT. 

I have followed the recommendation made by 213cobra and have now rolled an Amperex made in Holland 6DJ8 into my Orchid.
I know my new tube has not burned in at all yet.But out of the box I am hearing what he has predicted. I'd describe the change as a more fully fleshed-out tone. I suppose what that means for me is that the already very good midrange of the Orchid has filled out even more. The female vocal I just listened to has more depth and sounds warmer and more beautiful.
Really looking forward to the sound improving as this tube burns in.@213cobra Thanks for the recommendation!

I should have mentioned that I'm using the 5670/6DJ8 tube socket adapter available on-line. It did not require any circuit modifications.
Also, now that I'm a couple of hours in, and listening to some orchestral music, the new tube continues to provide a more fully fleshed out timbre. I'd describe it as the note fundamentals are fuller and a tiny bit more realistic, though I don't know how that is possible.

Anyone have a link to a high quality 5670 to 6922 adapter?
