I have only two 6SN7's - one is a top getter Sylvania



Not Yet There,

As I don't use the 6SN7 anywhere, I don't know much about them except that the 6CG7 was done to have a more compact version.

However, when I acquired an EICO HF-14 mono tube integrated (3-12AX7, 2-EL84, 6X4), I was given two 6SN7GTA's, one a bottom getter RCA and the other the Sylvania in the photo, which has a top getter. The thing is the flashing covers so large an area, the top mica is solid, and the getter is so pressed up at the top of the bottle, I can't see the getter shape or size. What kind of getter do these have? There is a marking on the base of,"3-48", but whether this is a 1948 tube I don't know. If so, this would be my oldest tube, the next being 1949 RCA 12BH7A's.

I do like the 6CG7, so I imagine it's cousin the 6SN7 can make some nice sounds as well.

Cheers,

Bambi B
