早期圆环吹喇叭PQ标7316 直代12au7 [复制链接]

(one of the best sounding 12AU7 ever made and very rare, excellent vocal reproduction)
(rich textured midrange, 10,000 hour low noise 12AU7 substitute, highly recommended)

"The first thing I noticed was how natural the human voice sounded.  
Not only do all the instruments sound more like themselves, but I
can hear each instrument and voice more clearly separated on that
proverbial soundstage.  I will never ever be able to go back to
"regular" tubes after hearing these."

这个管子的屏长确实比一般长屏的短，但和我手上的D环7316的屏是一样长的
是我发现了“短屏方环”管，还是7316都是这种屏？
请高手解答
