[AMPS] More amplifier experiments (score: 1): Author: jono@webspun.com (Jon Ogden); Date: Fri, 29 May 98 10:40:58 -0500; Gerrard, I stated that specifically when I wrote "no resistance in either L". I agree with you. Yes, I know. I thought this is what I was saying when I said it was invalid. OK so, let me present "co; /archives//html/Amps/1998-05/msg00644.html (12,761 bytes)

159. [AMPS] parasitics (score: 1): Author: jono@webspun.com (Jon Ogden); Date: Mon, 20 Apr 98 18:54:55 -0500; You are absolutely correct. Most of the time on HF, they are not a problem. However, even at VHF lead inductances and other circuits will KILL a circuit. I remember trying to build my fist VHF amp a; /archives//html/Amps/1998-04/msg00186.html (9,243 bytes)
160. [AMPS] parasitics (score: 1): Author: jono@webspun.com (Jon Ogden); Date: Tue, 21 Apr 98 09:32:10 -0500; I stand corrected. I think I meant the VHF tank circuit created by the stray capacitances and inductances in the tube, anode and tune C circuits. Yes, the output PI-network IS a lowpass filter. 73,; /archives//html/Amps/1998-04/msg00193.html (9,571 bytes)
