21. Re: [Amps] Ameritron AL80A (score: 1): Author: R.Measures <r@somis.org>; Date: Sun, 9 Jan 2005 00:27:32 -0800; The schematic is useful. At one time, the manual stated that it was okay to load and tune a 3-500Z at >500mA. However, the various manufacturers of 3-500Zs rate it at 400mA max. Although it will draw; /archives//html/Amps/2005-01/msg00138.html (7,290 bytes)

Re: [Amps] Ameritron AL80A (score: 1): Author: "Gary Smith" <wa6fgi@sbcglobal.net>; Date: Sun, 9 Jan 2005 09:10:34 -0800; In the 80-b manual it states the amp should be peaked, then advance the load control to (slightly) drop the peak for best linearity. Who needs the manual? E-mail me separate and I will send you a cop; /archives//html/Amps/2005-01/msg00145.html (8,268 bytes)

[Amps] Ameritron al80a (score: 1): Author: Wayne Smith <vo1ta.wayne@yahoo.ca>; Date: Sun, 16 Mar 2008 05:59:40 -0700 (PDT); I burned up the top of the plate choke on my al80a trying to load up on 17m.Still loads up on the other bands. I am wondering if I could replace it with the plate choke from the al80b which is availa; /archives//html/Amps/2008-03/msg00144.html (7,295 bytes)

It should work and avoid this problem. It wouldn't hurt to check it in place with a grid dip meter, if you have one available.; /archives//html/Amps/2008-03/msg00146.html (7,228 bytes)
