You mean the tube itself?

Just replace the tube with some silicon rectifiers ..( 1N4007 will do and cost nothing ) put  resistors of some 50 ohms in series with the diodes  , small r's 1/4 watts , they will act as fuses in case of shorts .  the cathode is dangerously high in voltage difference with the filaments tension .. try the amp without output tubes , must be silent unles your output trafo is gone 

you might also have a short or loss in the output trafo  but then this would pull your HT down .. measure Ht to see of it's normall 

good luck .. Benjamin , Belgium
