[TenTec] Modifyiing the Centaur...

[cherry@getnet.net]

James, the noisey internal fan does not even cool that well.
The noise is no worse than the QRM and QRN. I just try to ignore 
it. Also I use an external cheap floor type fan and it does a 
great job of cooling me, the Centaur, and my computer monitor.
It does blow any loose papers away. I have used these fans for 
years and they keep the Centaur cool. This fan does not need 
to be mounted above the Centaur. My fan just blows over the top 
of the Centaur. I have 572B tubes in my Centaur also. These tubes 
do not get as hot. The 572B costs more than the 811A.
