41. Re: [Amps] MFJ and Dahl (score: 1): Author: Scott Manthe <n9aa@arrl.net>; Date: Sat, 08 Dec 2007 20:42:24 -0500; I think pre-MFJ Ameritron amps were not as well built as post-MFJ Ameritron amps. The AL-84 is plastic and uses sweep tubes and the original AL-80 is junk compared to the "A" or "B" models. While it'; /archives//html/Amps/2007-12/msg00087.html (8,378 bytes)

(score: 1): Author: Scott Manthe <n9aa@arrl.net>; Date: Sat, 26 Jan 2008 18:01:37 -0500; Only the biggest lid in the universe would jeopardized our allocation on 60 meters by using an amp there. I certainly hope you mistyped, or the hobby is in worse shape than I imagined. Scott, N9AA __; /archives//html/Amps/2008-01/msg00211.html (7,883 bytes)

The amp will run cooler, the tubes will last longer and the performance will be about the same. What's not to like? 73, Scott, N9AA _____________________________; /archives//html/Amps/2008-04/msg00118.html (8,157 bytes)

My amp SEEMS to run cooler because it's not run up against the max ratings og the tube. There is no reason that it would actually run cooler. Thanks for pointing out my error. 73, Scott, N9AA; /archives//html/Amps/2008-04/msg00124.html (8,181 bytes)

While the cost difference seems substantial, you'll probably never have to replace; /archives//html/Amps/2008-04/msg00125.html (9,769 bytes)

I'm not here to debate that. I live in this world, not the best of all possible worlds, as Voltaire might say.
