You almost certainly have a grid to cathode short in one of the tubes.
Remove them one at a time and see what happens.

Subject: [TenTec] TT Centurion AMP failure
Help,
Was operating RTTY when my Centurion Amp quit working. The symptom is
that it shows 200 Ma Even in the Stnby position the plate current is 200
Ma
& the tubes are moderately red. The tubes are only a year old. Any idea
what might have happened? Looks like a trip a trip to TT.
Anyone with a Centurion Amp have this symptom?
Thanks,
Doyle/N4VV
