The triodes are a zero bias tube, and 200 mils sounds close for no bias
voltage. The amp should still make power, although in the wrong class of
service. If it does make power, you have lost your cut off bias voltage and
will have to trouble shoot that circuit. If both tubes are glowing about the
same color, good chance the bias supply is your problem or your bias voltage
switching. 73 and Happy DXing, Mike W2AJI Tryon NC

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
