- FWIW _ It appears with the help of several folks on this reflector and the AMPS reflector the Centurion oscillation problem on 40 meters is resolved. It also appears the "squeal " is fixed but may re

- Hi Hank, As a new owner of a 5 year old Centurion amp, I am curious to know the age of your amp ? I am running the Centurion with my Omni 6 Plus and have not seen either of the problems you encounter

- When I first got my Centurion, it had quite low output on just 15 meters. I called TT and the fix was...a longer jumper between the Omni VI and the Centurion. Also, I had to replace my fan and, yes,

- I don't recall the details of the original post but I seem to remember that the problem was on 40M and did not appear on other bands. This raises the question of how does the fan being loose relate t

- Squeal was a function of time on and heating , not the band of operation. The oscillation just started at about the same time . (In fact in retrospect - I think it was oscillating when new and I did

- But all in all, the Centurion only has a maximum of 10 to 12 dB of gain. Really not a lot to become unstable in my mind. Oh if one looses a parasitic suppressor then the gain at about 110 MHz goes qu

- My Centurion was in the shack for 5 years, and other than an early life fail of the bias transistor, I never had a single problem with it. Ran it with my Omni VI+ in RTTY contests, QSK CW, and even a
