1. [AMPS] Tank Tuning range (score: 1): Author: w8jitom@postoffice.worldnet.att.net (w8jitom@postoffice.worldnet.att.net); Date: Mon, 11 Aug 1997 16:05:19 +0000; In response to Rich's guess reduced Q would hurt matching range.......for a the ETO Q of 5.3 into 50 ohms..... and pi- tank inductor fixed at 21.57 uH and L inductor fixed at 7.255 uH..... 760 ohm lo; /archives//html/Amps/1997-08/msg00111.html (7,892 bytes)
2. [AMPS] Tank Tuning range (score: 1): Author: measures@vc.net (Rich Measures); Date: Mon, 11 Aug 97 20:30:43 -0800; ...snip... The output R (RL) of the pair of 8877s is approx. 3750V/(2A*2)=938 ohms. Since Q is defined as RL/XC1, and Q is given as 5.3, the reactance of C1 (which Mr. Rauch refers to as 'Cp') would; /archives//html/Amps/1997-08/msg00113.html (7,620 bytes)

[AMPS] Tank Tuning range (score: 1): Author: w8jitom@postoffice.worldnet.att.net (w8jitom@postoffice.worldnet.att.net); Date: Tue, 12 Aug 1997 07:25:41 +0000; To: <amps@contesting.com> Earlier you gave 1000 ohms, I used that figure. It certainly does. This operational example is for a "Q" of approx 5.3 into a 50 ohm load (using your Rp value of 1000 ohms); /archives//html/Amps/1997-08/msg00115.html (9,662 bytes)
4. [AMPS] Tank Tuning range (score: 1): Author: measures@vc.net (Rich Measures); Date: Tue, 12 Aug 97 05:28:57 -0800; To: <amps@contesting.com> 1000 ohms is the approx. RL for an anode V of 4k. However, this has nothing to do with the issue at hand. Does this wash?: - For a Q of 5.3 and RL=1000 ohms, the reactance; /archives//html/Amps/1997-08/msg00117.html (8,663 bytes)
