@firedrums. we're waiting on the first report on another thread.
@OP. Blackbase 6sn7w shorties in the balanced section. Quad RCA VT231 grey glass in the four left sections. Quad KenRad VT231s work well, too.--black glass or clear, either way.
Budget combo I like-- Sylvania 6sn7gta/b chrome top in the balanced and quad GE 6sn7gta side getter in the four left sections.
Really depends on your gear and preferences. These sound rich and a little warm with good mids on my gear.
An interesting combo was BGRPs in the balanced with a quad of mouse ears. Best I can describe it is "angelic," but thin.
Don't know why, but I use quads in the four left. (Sorry, I can't remember the numbers). Anyone mixing them up with good results?
