Sophia Electric Princess 274B Rectifier Variants

post #1 of 2
Thread Starter 

I'm interested in feedback as to the differing variants of the Sophia Electric Princess 274B rectifier.  Seems I have a GRAY tinted glass version with a smaller, less bulbous/rounded than another version which is totally CLEAR glass, larger, rounder.  There must be different production runs from differing manufacturers/countries (China/East Europe) .  Both are labeled "Sophia Electric Princess 274B".  Any others, comments????

Well, I may have been wrong about the glass color, seems this may be a natural aging and indicates the tube is about to fail, just as mine did.  BUT, there are still several manufacturers and wonder if anyone has experienced the different in sound and/or quality.
