Note: It is sceptical to read these factory datasheets for Russian tubes. These tubes is designed in USSR without any market and a competition. Product absolutely did not require any advertisment. And manufacturers indicate double smaller limits of time of service, warranty output Power, anode voltage, etc. This reduce its warranty responsibility before military customer. Really parameters is much better!
