    Hey guys i purchased my woo audio wa6 and sophia princess august last year and its getting close to a year old, I've noticed on the 274b princess rectifier the glass is becoming dark its sort of forming a dark tint but its only noticeable under direct light. I just wanted to ask if this is normal for the rectifier or if i should be concerned?

    I think it's fine. Just part of the tube age process. That's what I remember anyway?
