Favorite 300B: Sophia vs KR



Which do you prefer; S.E.T. Princess 300B Carbon Plate or KR 300B WE Clone?

I've only experienced NOS 40's/50's WE so my expectations are pretty high. Which do you think captures the essence of the WE most closely? I'm trying to keep the cost down as much as possible so EAT is not an option, as much as I was blown away by their KT88. I considered current WE but they're not in production until Spring 2011.

Gary,
I don`t believe this is universally true for the 300b.I have EML,AVVT,Shuguang BT and Takatsuki and none of these came with this type of warning/limitation of playing time.
I`ve used them with the amplifier on morning to night without any problems. Sophia Electric may have their own chosen restrictions.
Charles,
Just to be clear. I received no formal, written restrictions from Sophia. It was during a casual conversation with Sue that I received the five hour advise. Most of my friends, who have tube amplifiers, also try to minimize very extended sessions. I thought that this was common understanding. If this is unusual, I would welcome the thoughts of some of our more technically advanced members.

Have you talked to Sophia and what's their comment?

It looks like mega failure regarding quality control, can't be any differ.
