Re: [Amps] Different 3-500Z amplifiers (score: 1): Author: "David Craig" <davidhcraig@verizon.net>; Date: Tue, 28 May 2013 11:16:22 -0400; IMHO the graphite anode version puts out & maintains WAY MORE heat than the good old moly style. Just noticed recently RF Parts has a mention about that too. Dave N3DB Metal anodes were produced by E; /archives//html/Amps/2013-05/msg00191.html (11,047 bytes)

Re: [Amps] SB200 on 6M (score: 1): Author: "David Craig" <davidhcraig@verizon.net>; Date: Sun, 02 Jun 2013 19:31:52 -0400; I'd go with 1/4" flat strap in a "U" with a pair of 100 ohm 5w MOX in parallel. But, FWIW, I wouldn't use 572Bs either, though I am positive the latter comment will draw fire. 73 N3DB Dave I'm conver; /archives//html/Amps/2013-06/msg00007.html (7,463 bytes)

Re: [Amps] SB200 on 6M (score: 1): Author: "David Craig" <davidhcraig@verizon.net>; Date: Mon, 03 Jun 2013 10:01:37 -0400; Paul, your question is certainly clear enough here in reference to "tube geometry & circuit layout". Unless of course you've decided to play "blocks" with the SB200 internals. With that said, I did p; /archives//html/Amps/2013-06/msg00019.html (10,642 bytes)
64. [Amps] Glitch resistor in tank compartment (score: 1): Author: "David Craig" <davidhcraig@verizon.net>; Date: Fri, 09 May 2014 19:28:07 -0400; Hello All, Sounds counterintuitive as I know the Z-50 in the SB220 & others who covert them to 6m monoband amps do it but want to throw it out there for comment. I've got a Aerotron Navy surplus 3-40; /archives//html/Amps/2014-05/msg00050.html (7,468 bytes)

Re: [Amps] Glitch resistor in tank compartment (score: 1): Author: "David Craig" <davidhcraig@verizon.net>; Date: Fri, 09 May 2014 20:01:08 -0400; Thanks Carl- I remember your mod, I'm just worried a bit because this will be much closer to the tank coil than the SB220 had. I replace RFC-2 in the SB-220 with a 25W glitch and never had a problem; /archives//html/Amps/2014-05/msg00053.html (9,353 bytes)

My Harbach purchases of similar size arrived with a plywood base as I recall, an if my CRS-ridden memory serves correctly, this was then encased in a he; /archives//html/Amps/2018-01/msg00109.html (10,267 bytes)
