1. [AMPS] High current filament circuits (score: 1): Author: nx7u@primenet.com (Scott Townley); Date: Tue, 10 Nov 1998 06:53:06; One of the principle maladies of my 2x 3-500z HB amp I've acquired is low filament voltage at the tube socket--all of 4.3V. The filament xfmr is in the main power supply cabinet, going thru a run of; /archives//html/Amps/1998-11/msg00150.html (9,195 bytes)
2. [AMPS] High current filament circuits (score: 1): Author: measures@vc.net (Rich Measures); Date: Tue, 10 Nov 1998 08:18:45 -0800; Sometimes. . Crimps are not as reliable as soldered connections. A pair of #10s has around 60mV drop per foot at 30A. 30A-rated connectors with the wires soldered /not crimped/ to the connector-pins; /archives//html/Amps/1998-11/msg00156.html (9,394 bytes)

[AMPS] High current filament circuits (score: 1): Author: km1h@juno.com (km1h@juno.com); Date: Tue, 10 Nov 1998 11:46:28 -0500; I NEVER rely on crimp connectors since I do not have the proper crimping tool. Plier crimping only is asking for trouble. Always crimp as well as you can and then solder. One way to tell if you have; /archives//html/Amps/1998-11/msg00157.html (9,302 bytes)
4. [AMPS] High current filament circuits (score: 1): Author: Peter_Chadwick@mitel.com (Peter Chadwick); Date: Tue, 10 Nov 1998 17:00:02 -0000; Even with the proper compressed air tool, I wouldn't be happy with crimped joints at 30amps. If you can use high temperature solder (or even silver solder) and shakeproof washers where screw terminal; /archives//html/Amps/1998-11/msg00158.html (7,654 bytes)
5. [AMPS] High current filament circuits (score: 1): Author: dhaupt@bewellnet.com (Dave); Date: Wed, 11 Nov 1998 23:27:27 -0600; Scott, before abandoning crimps in favor of solder, or swapping out #10 for #2 welding wire, you should be able to actually measure where the drop is happening. On your bench arrangement, try baring; /archives//html/Amps/1998-11/msg00173.html (9,475 bytes)
6. [AMPS] High current filament circuits (score: 1): Author: km1h@juno.com (km1h@juno.com); Date: Thu, 12 Nov 1998 01:36:24 -0500; SNIP The Johnson socket used from the days of the 4-250A to modern times has always been prone to loosing contact tension on the filament pins. Most often due to poor air flow. One quick cure is to d; /archives//html/Amps/1998-11/msg00176.html (9,003 bytes)
7. [AMPS] High current filament circuits (score: 1): Author: g.jones@bom.gov.au (Graham Jones); Date: Fri, 13 Nov 1998 08:26:35 +1100; -- To: <amps@contesting.com> snip Agree. We shouldn't be too quick to blame crimp connections for high losses. I recall from my early days working at Collins radio as QC engineer that "properly" crim; /archives//html/Amps/1998-11/msg00183.html (10,414 bytes)
