Bobf, They are large halo getters all tubes marked 66-13. I need to correct the S/E socket position, they are the two inside sockets the outside are bal!! sorry!! I also have some "other" tubes I bought to tryout.
Orelayer I put a set of Jan Phillips 6922's ( they were given to me by the Ray dealer to try) in just to compare with Amperex, there is NO comparison, if you thought the Jan Phillips were an improvement you will be shocked at how much more information any Amperex tube will provide, you don't know the quality of sound your system is capable of because those tubes aren't letting you hear what's already there!!! Best bang for the buck Bugle Boys, for a little less rich sound Orange dimpled getter A frame Holland. For me politically correct is less important than you getting rid of those tubes, I think the Ray is a little on the thin side(in my system) and begins to shine with a lusher tube!!!
