I can also confirm this from personal experience. I ended up throwing a few of them (bought from eBay) because they were so noisy

I will confirm that "...Strong rectifiers like the 596 also quiet down cheaper 6080 tubes". Unfortunately, I can't find affordable 5998 nor reasonably priced 7236 (if you have leads, let me know). I am using THOMPSON-CSF 6080WA and they are affordable and quiet. Do anyone else have any...

I went through an exhaustive exercise, labeling all the tubes, swapping them left-to-right, and with different combinations. I had no problems with the 6SN7's I've got but had difficulties with a large batch of 6080's I had. I am interested to hear how your exercise is going so far!

What amp do you use? What preAmp did you use before WA22? I presume the WA22 does better?

I wonder how they sound... has anyone ever used this in their amp?

Thank you for your response but I have a clarifying question: did it eliminated the hum on your wa22 or your other high end equipment?

I have SIGNIFICANT problems with hum. How do you do a "dedicated power line"? Have others used power supplies that help with the problems with "hum" on their WA-22?

why do you ned adapters for the standard 6080s and the 5u4g?

Thank you SO MUCH for your post... I wished I read this before I tried to get Sylvania 6080 and RCA 6AS7 working... it was IMPOSSIBLE to get rid of the hum... Can you please help me understand how and why do we run 6BL7 in pairs?
