Howdy, Has anyone tried the new KT77 from JJ? I'm thinking of trying them in a glorified ST70. I listen primarily to bluegrass and mostly female voice. I am currently using Sovtek EL34's in favor of Electro Harmonix EL34's. I was also thinking of trying some 88's or 98's. While I'm at it, would I need to change bias, and if so how would I know what to set it at? Thanks for helping with a probably (way to simple question), but I have to tinker with something in between reading all the great material that has been suggested on this forum. Kindest Regards, Jayman:)
