[AMPS] Ten Tec Centurion Ampifier

[Doyle/N4VV]

Help,
    I am having a problem with my Ten Tec Centurion amplifier.  For some
reason the loading has changed for all bands 160 through 10 meters.
    For example:
On 10 meters loading use to be 4 now 3
On 40 meters loading use to be 8 now 4
    The loading is lower on all bands.  Removed the cover & checked the
capacitor, the knob had not slipped.
    This tests were done using both a Bird KW oil filled dummy load, plus
antennas.
    Bypassed the antenna tuner.
    Changed coax between the Omni VI & amp.
    Anyone on the Reflector had a similar problem, bad tube??????  I can
still get 1 KW out of the amp.
    Appreciate any help & thanks.
