1. [Amps] AL-1500 filter caps (score: 1): Author: "Dave Hachadorian" <k6ll@arrl.net>; Date: Wed, 17 Oct 2012 21:41:31 -0700; A friend's AL-1500 started blowing fuses after the two minute timeout. I isolated the problem to the filter cap board. After pulling the board, I found that two or three caps had vented their guts on; /archives//html/Amps/2012-10/msg00099.html (7,657 bytes)

Re: [Amps] AL-1500 filter caps (score: 1): Author: Bill Turner <dezrat1242@yahoo.com>; Date: Wed, 17 Oct 2012 22:30:01 -0700; REPLY: So you're going to put in the exact same resistors which failed in the first place? I would think you'd want something better. 73, Bill W6WRT _______________________________________________ Am; /archives//html/Amps/2012-10/msg00100.html (6,950 bytes)

The 8 capacitors are running right on the edge as well. They are 450V rated and the plate voltage is 3600V. On days when the incoming mains is a little higher, it is not uncommon for; /archives//html/Amps/2012-10/msg00102.html (9,646 bytes)

Re: [Amps] AL-1500 filter caps (score: 1): Author: "Paul" <w8aef@q.com>; Date: Thu, 18 Oct 2012 08:51:33 -0700; If the amplifier is 30 years old like my Alpha 76A the components probably are properly rated for the job. de Paul, W8AEF Have they changed the resistors to ones properly rated for the job?
