There could be several causes:
1) check the transformer tap settings for the proper 220 range voltage,
2) are you running the amp on 220 vAC ?
3) one or two power supply HV filter caps may be shorted
4) check the voltages with an accurate DMM, there is a calibration pot on the
inside of the front panel which will adjust the voltage reading on the amp’s
meter. There was a run of the Centurions (23 years back) that had bad HV
xfmrs…..mine shorted out about 8-9 years ago. Fortunately, Ten Tec was still in
fine shape at that time and for a psaltry sum of money ($500) I received a
brand new HV xfmr. You might have something brewing in yours and it just has
not completely failed yet.
Good luck……….what really matters is what is your Po into a 50 ohm load……. key
down you should get between 1100 and 1300 watts output (not pep)
Drop me a line if you have any questions. I have rebuilt my Centurion twice
