[TenTec] Titan/Alpha and Centurion amplifiers

[k0bx at arrl.net]

At home I have a Centurion 422 Amp built in 1995.  I bought it two years ago for 
$1300.  I drive it with a PRO3, and during last weekend contest ran about 750 
watts output.  The computer keys the amp, amp keys the rig making for a very 
smooth QSK.

Also I operated from our club station.  There I used a PRO3 driving a 
Alpha8410.  This is the new one with the 4CX1000A's instead of the 4CX800's.  
The rig keys the amp.  The QSK was good but either it was very quick or just my 
ears but the CW seems to be choppy.  The other operator was using break-in when 
I took over.  I think that was the reason.

Using the Alpha I ran between 1200 and 1400 watts output and the amp never got 
warm.  Several European stations that were running stopped and told us that we 
had a big signal!  I never had that happen at home.  


Bottom line, go with the Alpha at $5000 (if someone else is paying for it) or a 
Centurion if you can find a good used one.

Thanks Barry.

I would want it to be the 425 to match the "cosmetics" of the CorsairII 
and OmniVI.
