[Amps] Ameritron ALS 500M (score: 1): Author: "Mike Feher" <n4fs@eozinc.com>; Date: Sat, 21 Nov 2015 10:55:06 -0500; I probably should have asked these questions prior to buying one, but, one just arrived yesterday and it will still be helpful to get some user input. So, I just bought the subject amp and the matchi; /archives//html/Amps/2015-11/msg00138.html (7,314 bytes)

Basically it has served me well and has never shown a heat problem. I have never; /archives//html/Amps/2015-11/msg00140.html (9,947 bytes)

It will be easy enough to measure the two tone IMD as a function of voltage. I assume the higher order ones will not matter as they should be pretty far down, but, possibly; /archives//html/Amps/2015-11/msg00150.html (8,807 bytes)
