[TenTec] centurion

[David Propper]

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
