In Reply to: RE: Which version of the M60 do you have? It makes a difference. posted by ozzyboy on March 26, 2017 at 15:51:21
You'd be much better off with facts from Ralph re what tube does what than conjecture from me. But the concepts are correct. I find it difficult to understand how the two outside tubes among the rear 3 (the tube on the far L and the tube on the far R) are together to form the dual-differential cascode, because those tubes are interconnected in a rather complex way, and I doubt that Atma would have them separated by the presence of the middle tube. It certainly could be the case, but I don't know for sure. That's why I suggest you ask Ralph.
By the way, what is a "Sophie" tube, and in what way are its dimensions different from a 6SN7GT, GTA, or GTB?
...to the Sophia 6SN7.

William Bruce Cameron: "...not everything that can be counted counts, and not everything that counts can be counted."
Took that quote from the Sophia website. It's an odd one, because CV32/33 and CV181 are in fact NOT 6SN7s in any way. I have seen CV181s, and they generally resemble those Sophia tubes being sold as 6SN7 replacements. They are electrically different from a 6SN7, and that's why they will sound different from a 6SN7 if plugged into a circuit designed for a 6SN7. On the other hand, CV1988 is a legitimate alternative name for a 6SN7. I have some Mullard/Brimar tubes that are labeled "6SN7GT/CV1988". I have no idea what Sophia is smoking.
The Sophie tube is an Audiophile tube that is taller and wider than the normal size 6SN7 tubes.
