Hi. Both my pre (Concert Fidelity) and power (Lamm 1.2s) use 6922s. I'm pretty sure that I am needing a tube replacement on one channel on the Lamms and am thinking of EAT EC88s (for the Lamms and possibly the CF as well). Are people using these - or have you tried them and if so what is your opinion of them and what is the sound like?
Also how well do they compare with the better NOS tumes around?
