Best 811A Available Time Owned: more than 12 months.
The Svetlana is the same as the Russian Ryazon G-811A tube. It is properly made and will likely outlast any Chinese 811A that is your only other choice available for sale. The plate ICAS dissipation rating is 60 watts and not to be confused with the Russian CCS rating of 40 watts. A ham has stated he is still using four of these tubes 20 years later and produce full power output. Get a quad while old stock supplies last.
Note- Chinese 811A have improved over the years and current manufacture are superior vs older Chinese 811A tubes. However, Chinese Shuguang are no longer manufactured, Psvane is only manufacture left with unknown quality.

They are "ok" Time Owned: more than 12 months.
Have had them in my AL-811H for about 1 year ,
The china tubes similar to Svetlana, but my RCA tubes are doing best !
Have on the way Amperex tubes and it will be fun to measure them also.
