Ive been running a hair over 3000V on my 2M amp that was a pull when I built it 25+ years ago. It still will do 1800W out.

(score: 1): Author: "Steve Katz" <stevek@jmr.com>; Date: Thu, 6 Sep 2012 17:16:28 -0700; I think the temp rating of those cutting boards is fairly high, as you can place meat that was just cooked at 400F directly on the board without damage or discoloration. Or, at least I do that! WB2WI; /archives//html/Amps/2012-09/msg00097.html (9,743 bytes)
