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?
