5ar4 rectifier tube


I’m buying some backup 5ar4’s for my primaluna evo 100 preamp.  Upscale audio’s website says the Gold Lion isn’t suitable for this preamp. I like Gold Lion but there’s no explanation why.  There’s only one other choice on their site.  I also like Upscale audio.  Advise is appreciated..

I love the mullard big base on my Allnic phono stage.  Surprised me what a difference it made verses stock.  Great sound and reliability.  

Here's another tube vendor that I have not checked out yet (recently discovered them).

@dekay , I like that he specifies that some of the tubes he sells are used. . . .

I've had no problems with Gold Lion 5AR4s, but I would use what the manufacturer recommends.  A friend of mine continually rolls tubes and has managed to trash a number of expensive amps.  The manufacturer of one amp specifically advised against using a certain brand of 300B.  He did anyway and blew the amp--twice!!
