gelle... other dealers will have the Siemens tubes and they regularly come up on Ebay. "Farawayfinds" on Ebay has an excellent selection from the 6922 family. I have the Orchid as well and all the flavors of 6922 fit comfortably with a pin adapter...

PS, Generally speaking, the earlier production Siemens valves -- like many other brands -- are superior to the later production.

gelle... Siemens made valves are from German and the European 6922 (American designation) equivalent is the e88cc. Many tube dealers, such as Brent Jessee, carry them. Top of the Siemens line is the CCa, followed by the e188cc (American 7308), the... 
Mitchum or Blackburn for the Mullard 6922?
Wow, it took a long time --150 hrs or so -- for my Mullard e88cc to break in. Now the bass is fleshed out, the highs smoother and soundstage more dimensional. Altogether a more balanced sound. Yes, magical, richly satturated midrange, if without...

Mitchum or Blackburn for the Mullard 6922?
Ah, yes the "magical midrange." I agree. Yet in my Blackburn, the mids and upper mids seem over-emphasized. I prefer to tone it down a notch or up the bass and midbass. Could be a mismatch with my system, I suppose. Does the Mitcham have as much d...

tvad... Have you compared the Blackburn and Mitcham e88ccs? 
Mitchum or Blackburn for the Mullard 6922?
Tvad... On the contrary, I'm "satisfied" with most of the 6922s I've tried. Each has its own character and I appreciate their respective ways with music. On occasion I change tubes when listening to particular types of music. My generalist tubes t...

The Blackburn Mullard is fully burned in. The weakness of the tube is the anemic bass and midbass, producing an unbalanced sound spectrum. The upper mids and highs are glorious, however, detailed, harmonically layered, 3-dimensional and natural so...

Ha ha ha. Now I'm worndering what Mitchum production sounds like. 
Mitchum or Blackburn for the Mullard 6922?
Yes, it's IEC Mullard, although the IEC is patchy.

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.
