I just rolled in a 274B rectifier and paired 6SN7s into my amp and wow are they good:

Hey there,

Ive been running a "Grade A" Sophia Electric 6sn7 Blue glass in my Icon Audio PS3 MK II for about the past 7 months. It sounds great! In my opinion it sounds better than the David Shaw CV 181 "HIFI Vale" that came with the unit. However, just yesterday, it failed me. One of the triodes crap  the bed, the right channel in this case. I got a loud pop and then there was next to no audio passing through the right channel. it was at this point that i had also noticed microphonics from it. So a nearly $200 tube for 7 months that could have damaged other components in my rig while it was at it. Unfortunately, id say in my experience here, they are unreliable. I emailed Sophia Electric and explained this to them and asked them for an exchange for a new tube or a discount on a new one or something to help me out here even though its out of the stock 30 day warranty; well see what they have to say, ill keep you guys posted if anyone is interested.

Interested....
