James,
My previous amp was a Centaur. Very nice little amp, except for a loud fan.
I never had the problem you are discussing. I did use the QSK cabling to
the TT rig via the TN and EN jacks on the back of the radio.
Aside from your noise issue, these amps should have had 572b's in them
instead of 811's. Also, a good pabst fan running a bit slower is a popular
mod. The 572's are a drop in replacement. The four wimpy toggle switches
on the front panel are also a common replacement headache.
If you are still having trouble, suggest you call TT service.

James,
Sounds like a relay but even so, shouldn't make a "racket". I think
there is also a relay for the fan in the Centurion, it's very audible
in my Centurion, but it's infrequent.. Certainally not with every dit
or dah.
My Centurion and Orion 2 are fairly quiet. I have the keying cable to
the Centurion and also the "IN" and "OUT" which is for QSK.
Good luck, I'd check the relay. Also, you don't need the amp if you
are practicing.

Are you guys saying your amps make a racket on every
dit and dah you pound out?
I am just learning CW... slowly... maybe surely... and
wonder if I need to look into this on my own Omni VII
and Centurion amp combo.
Should I worry? Or just keep practicing?
Thanks. ========= James - K8JHR ===============
