Mitchum or Blackburn for the Mullard 6922?
I'll look for the other numbers in a while. The tube's fermenting in my dac at the moment and sounds rich, detailed, 3-dimensional and quiet.

Best 5670 to 6922 tube adapter is made by Garage 1217 (garage1217.com).  Superior to every other adapter that I have seen. However, please note: the pin holes are tight and therefore the tube pins must be straight in order to facilitate placement.

petg60... Mullard e88cc code is B5H3.

Anything to offer about the Siemens D-getter e88cc/e188cc compared to the halo, solid disk and dimple disk?

A 1958, solid-disk-getter e88cc sounds as likely to find a great auk.

The Tube Museum entry I hadn't seen. Sounds like a voice of authority. Thanks for the reference.

But not just any 6922. The early Siemens is sublime.

Ok, interesting information. I have tried many different flavors of 5670 tube, some obviosly better than others, however, I will never go back to that tube after adapting the socket to emply the 6922. What a glorious difference that made in every ...

petg60... by the way... thank you! 
Difference in sound between Siemens e88cc and e188cc?
petg60... What do you mean by "energetic?" Do you mean the signal sounds "faster" or do you mean more dynamic (wider range of volumes/signal variation)? Or both? Does one seem more "natural" to the sound source?

petg60... Can you offer a comparison of the Mazda/RTC e88cc/e188cc with the Siemens and Amperex equivalents? 
Difference in sound between Siemens e88cc and e188cc?
petg60... please elaborate. Does the Siemens e188cc have the same great clarity, detail, imaging, naturalness and dynamics as the e88cc, but a more saturated tonality, similar to Amperex? I find the e88cc seductive, but somewhat astringent.

PS. Yes, I've looked at Joes Tube Lore and VTV, etc. Interested in expanded commentary and user experience.
