@OP - if the tube is a genuine 5AR4 there is no reason why any brand should not work. However there is a huge spread of opinion on whether the entire family of 5--4 and 247 rectifiers are cross compatible, even though they are pin compatible.
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..
