Linlai 6SN7


I am using Linlai 6SN7 in my Supratek Cabernet preamp. I have noticed that the tubes run vey cool to touch even after four hours of use. Is that normal for these tubes? Thanks.

@dekay, interesting question about glass thickness and heat. I’m  also curious about this. I never really thought about that,until this thread popped up. 

The Linlai E 6sn7 are the coolest tubes I own. Thank you @atmasphere for explaining this.
