Hello,

I just come across someone selling UE 211 triodes. Do you guys other sources ?

This is the first time I have seen them before. I was told by someone at Audionote that there better than the GE VT4C's or 845's. I guess they are used in the Ongaku etc. But supply must be a real problem and getting them at good quality. I would of bought them if I hadn't been so tight with money just moving house so I have had to sell my Mullard's GZ 37.

I was told by audionote that the Tungsol 5687 was the best sounding they have heard. There probably is certain versions military etc.

I had 2 pairs of United 211....Never compared with other 211 from United but I was told these are best. :D It's JAN Navy CUE38111.... I've various 211/VT4C tubes from GE...Replacing the GE VT4C with the United CUE38111 yeilds overall sonice reult...More powerful low-end as well as highs...Better in any way compared to all the different version of GE's that I had.
