1. Re: [Amps] copper or silver in tank circuit? (score: 1): Author: "Larry Carman" <lncarman@swbell.net>; Date: Thu, 16 Jun 2005 07:59:14 -0500; I was told by a pro amp builder to leave out the silver and use copper only in the tank circuit. Reason: because it helps prevent parasitic on the higher frequencies. I'm speaking of HF amps working; /archives//html/Amps/2005-06/msg00120.html (9,176 bytes)
2. Re: [Amps] copper or silver in tank circuit? (score: 1): Author: G3rzp@aol.com; Date: Thu, 16 Jun 2005 09:17:23 EDT; I think the idea is that silver oxide and silver sulphide are conductors, while copper oxide isn't. So the coil Q stays up after the atmosphere has been at work on it. Wheter or not you can tell the; /archives//html/Amps/2005-06/msg00121.html (7,160 bytes)

If that's the difference between a amp that's stable and unstable, them there's something much more fundamental needs fixing. I recall an article in RF D; /archives//html/Amps/2005-06/msg00126.html (8,113 bytes)

Copper Oxide rectifiers were invented in the USA in the early 1920's. The British Westing; /archives//html/Amps/2005-06/msg00130.html (7,591 bytes)

Sure plating has an effect on UNLOADED Q. But, once it is loaded, the load resistance is the dominating factor when it comes to Q of a HF amplifiers tank cir; /archives//html/Amps/2005-06/msg00131.html (10,892 bytes)
