Tube data for current manufacturers?

Hi,
Data for new valves by current manufacturers seems to rely on old datasheets.
I can't seem to find any cuurent data on Sovtek valves, for example - 5881/6L6WGC. What I have found is old data that says the 5881 has a peak Ua of 360V and the 6L6GC has a peak Ua of 500V.
The Sovtek 5881/6L6WGC is one tube. Any clues as to where i can get current datasheets from Sovtek and others that don't have obvious websites?

Thank you,
Robert.

P.S. - Perhaps I have missed something, but I can't seem to find a search function on this forum - lots of browsing? (I've not logged in for a long time)

P.P.S. - I've found the forums search at the bottom 🙂
 
There's a "search" button on the upper right, too.

New Sensor seems to provide about zero in the way of real data. I guess that explains the high prices. You might email them to see if they'll cough up a data sheet. Most other new brands are better documented.
