Can a 6SB7 replace a 6A7/6A8?

If you didn't mind using loctals, I see the 7S7 has a higher transconductance (525 umhos) than the 7J7 (290 umhos) and about the same as the 6A7 (520 umhos). Not as high as a 6SB7Y, though.
The 7J7 and the octal 6J8G were used in many 1940 Philco models. -- Ron Ramirez Ferdinand IN
