1. [TenTec] Fw: Ten-Tec 411 Centaur Amp Problem (score: 1): Author: "CSM$r$ Gary Huber" <glhuber@msn.com>; Date: Tue, 1 Jun 2010 11:42:22 -0500; Ooops, I should have stated the input resistor as 25W at 150 Ohms. Still it is in parallel with the cathodes of the THREE grounded grid 811s, so the input SWR should be 3:1 or less when the source im; /archives//html/TenTec/2010-06/msg00002.html (15,505 bytes)

Johnson" <geraldj@weather.net>; Date: Wed, 02 Jun 2010 14:48:31 -0500; A single 811 usually has a cathode Z of about 200 ohms, so three in parallel would be 67 ohms and put that in parallel with 150 ohms makes 50 ohms. The low pass filter has the only reactive component; /archives//html/TenTec/2010-06/msg00018.html (8,593 bytes)
