[Amps] AL-80B Trouble

[Scott Manthe]

This seems to be a very common occurrence in later Amperex tubes. The 
tube is at fault, not the amp- replace the tube and you'll likely get 
good service from the amp.

My fear is if I just replace the tube, I will  end up back to square one over time.  Is  there any trouble shooting guide regarding the Amp?  I am looking for a document or notes  indicating voltages, along with tips of what to look for.
