Hey mab, Mephistopheles rides again! How can you tempt a poor fellow so?...How could I possibly part with the DRs? (Mind you, I do have a spare pair - unfortunately one has no writing on it, so had to take it on trust...will probably move them on...).
So it looks like it's adapter-making time once again - 'She who must be obeyed' thought all was just about wrapped up. As did I!! At least those nice fat pins will be much easier to work with than the C3gs'...
Ah well, I can always blame you, mon ami (not that I take much persuasion - they look SO beautiful!). With matched pairs going on ebay for not too much (one seller also with 'best offer'), methinks I am LOST (past saving, even)!
Here's a link to an interesting article comparing them to some of the best 6SN7s....
Actually, you don't have to build adapters, as you can buy them ready-made (the 6CG7 has the same pin-out as your DRs):
While I do not have a smoked-glass Brimar 6SN7GT, I do have a Brimar 13D1 (which is essentially a 25SN7GT) and the Sylvania 6SN7GT referenced in this article, and while I think they are very good, I would not rate them among the very best. But of course, this is just one man's opinion based on old ears and modest gear. :)
So in my opinion, if you want "curvy" CV181s of similar quality to your DRs and C3gs , I think you should get "real" CV181s:
