1. [Amps] Ten-Tec Centurion fan replacement (score: 1)
Author: Rudy Bakalov <r_bakalov@yahoo.com>

I was wondering if anyone has experience replacing the Centurion fan. My fan is old and has a bearings problem so it is time to replace. I'd like to take the opportunity to replace with a high-CFM ra

Hello, I have an old Ten Tec Centurion with brand new matched pair of 3-500Z tubes. I plan on running the amp for 48 hours during the upcoming CQ WW RTTY contest. My previous experience with the amp

Good question too! I guess the fundamental question is why did Ten Tec select 90 CFM fan instead of 250 CFM. If you put too much air around a tube, won't the aerodynamics of the convection structure

"I guess the fundamental question is why did Ten Tec select 90 CFM fan instead of 250 CFM." Assume amp designed with 250 cfm fan and going to review to marketing, this might be the conversation: Mark

Rob, I am the second owner of this amp and don't know its age. It is the grey model. I can certainly look up the serial number when I am back to VE3 where my contesting QTH is. As far as mode goes, m
