1. [Amps] heat sinks (score: 1): Author: Larry <larry@w7iuv.com>; Date: Tue, 13 Nov 2018 10:07:36 -0800; Anyone got a good source of aluminum heat sink stock? I know about Heatsink USA. Their prices are steep but not prohibitive. Unfortunately by the time I add on the shipping and handling charges, it n; /archives//html/Amps/2018-11/msg00054.html (6,755 bytes)

3. Re: [Amps] heat sinks (score: 1): Author: Manfred Mornhinweg <manfred@ludens.cl>; Date: Fri, 16 Nov 2018 20:39:45 +0000; Larry, my reply won't be the most helpful, but anyway: Make a highly efficient amplifier. Then you don't need a huge heatsink. Other than this, Heatsink USA is where I have bought heatsinks several t; /archives//html/Amps/2018-11/msg00058.html (7,907 bytes)
4. Re: [Amps] heat sinks (score: 1): Author: Larry <larry@w7iuv.com>; Date: Sat, 17 Nov 2018 13:50:56 -0800; Manfred, I've played with some "highly efficient" amps. Don't like the complexity. For me at least, simpler is better. I can throw together a simple inefficient AB linear in a heartbeat. Electricity; /archives//html/Amps/2018-11/msg00059.html (9,533 bytes)
5. Re: [Amps] heat sinks (score: 1): Author: "Roger (K8RI)" <k8ri@rogerhalstead.com>; Date: Sun, 18 Nov 2018 20:50:49 -0500; Now here is some nostalgia. In the early days of SS, or at least a couple decades back I had a stack of big heatsinks. Some were a foot wide and longer than that I have no recollection of where they; /archives//html/Amps/2018-11/msg00062.html (10,998 bytes)

Re: [Amps] heat sinks (score: 1): Author: Manfred Mornhinweg <manfred@ludens.cl>; Date: Mon, 19 Nov 2018 14:45:10 +0000; Ron, With the high cost aluminum I can't help but wonder if something like copper sheeting could be used instead. (1/4" thick or so) Copper is nearly twice as good a thermal conductor as pure alumini; /archives//html/Amps/2018-11/msg00064.html (9,456 bytes)
