Power Amp

My power amp keeps burning up the power tubes.  I get maybe 4 months out of them  . I have use three different type of tubes that are recommended for the amp. Can anyone help, why this is happening, are all of the power tubes bad?

Here is solid advise , Buy a Ayon integrated amp why it it microprocessor controlled you bias it by holding in the button on back and each tube is run optimum ,and saves the tube life ,
when a tube does go ,it will shut off and let you know exactly which tube it is you wait 20 minutes , the amp rebias allthe tubes 
and ready to go , you shut off when not using very dependable .
