1. [Amps] Pi-L Check (score: 1): Author: "wc6w@juno.com" <wc6w@juno.com>; Date: Thu, 17 Feb 2005 03:40:24 GMT; Good evening to the group, I've cobbled together a Quick Basic Pi-L program that calculates the coils at the nominal output impedance (52 ohms) and at the high end of the wider bands. It then recalcu; /archives//html/Amps/2005-02/msg00556.html (7,084 bytes)

Re: [Amps] Pi-L Check (score: 1): Author: Ian White G3SEK <G3SEK@ifwtech.co.uk>; Date: Thu, 17 Feb 2005 08:32:47 +0000; There is an Excel spreadsheet on my website, which does both Pi and Pi-L output networks (but not input networks). It can also include stray L and C, and a parasitic suppressor if you wish; but you c; /archives//html/Amps/2005-02/msg00558.html (7,884 bytes)

Re: [Amps] Pi-L Check (score: 1): Author: "Phil Clements" <philk5pc@tyler.net>; Date: Thu, 17 Feb 2005 17:47:19 -0600; John, In the 23rd addition (and others) of the Bill Orr Handbook "Radio Handbook," on page 14-22 there is a chart (Figure 44) that shows cathode circuit values for grounded-grid amplifiers. Range is; /archives//html/Amps/2005-02/msg00567.html (7,730 bytes)

Re: [Amps] Pi-L Check (score: 1): Author: "wc6w@juno.com" <wc6w@juno.com>; Date: Fri, 18 Feb 2005 02:37:23 GMT; Hi Phil, If you check the math on that table, I believe that you will discover that the C1 & C2 values from 75 ohms through 200 ohms are interchanged. It "looks" correct as printed because the large; /archives//html/Amps/2005-02/msg00571.html (8,165 bytes)
