1. [TenTec] Centaur (score: 1): Author: tims@hhs.net (Tim Soxman); Date: Wed Apr 16 17:30:26 2003; Hi, Thinking about retubing my Centaur with 572Bs, as I recall there was some discussion on the process but the gist of it escapes me. Any comments pro or con and tips? Tim W3ZVT; /archives//html/TenTec/2003-04/msg00398.html (6,343 bytes)
2. [TenTec] Centaur (score: 1): Author: cherry@getnet.net (Jim FitzSimons); Date: Wed Apr 16 18:47:16 2003; Tim, they work great. The power supply will not put out any more power. For SSB you can put out more power since the average current is lower than CW or RTTY. I got a matched set of three 572B's for; /archives//html/TenTec/2003-04/msg00402.html (7,232 bytes)

This usually gave 400 watts output. I never got 500 or 600 watts output. Carl Moreschi N4PY; /archives//html/TenTec/2002-02/msg00329.html (8,407 bytes)

10. [TenTec] Centaur (score: 1): Author: aa4nn@juno.com (Joe L Blackwell); Date: Thu, 21 Feb 2002 16:38:56 -0500; You need to put some watts in to get watts out. Nowhere have I seen what has been the amount of drive applied to get, say, 400w out.
