1. [AMPS] Calculating input impedance and drive requirements? (score: 1): Author: kd5izi_tech@yahoo.com (Randall DuCharme); Date: Fri, 19 Oct 2001 06:55:14 -0700 (PDT); Greetings gurus, I'm a little bit lost.... I'm unsure as to the correct mathematics and methods to calculate the input impedance and drive requirements of an amplifier stage. Seems that I need this i; /archives//html/Amps/2001-10/msg00395.html (7,449 bytes)
2. [AMPS] Choke input PS question (score: 1): Author: kd5izi_tech@yahoo.com (Randall DuCharme); Date: Sun, 21 Oct 2001 18:46:02 -0700 (PDT); Greetings, I'm building another power supply for my amplifier project. I originally set out to use a capacitor input design commonly used but have since (tonight) found a large (13H) choke. I was tol; /archives//html/Amps/2001-10/msg00416.html (8,182 bytes)
3. [AMPS] Choke input PS question (score: 1): Author: kd5izi_tech@yahoo.com (Randall DuCharme); Date: Mon, 22 Oct 2001 06:43:45 -0700 (PDT); Interesting, And here I thought that the primary reason many modern amplifiers lacked heavy chokes was to save weight, space, and cost. :-) Something like this would have never occured to me. It's su; /archives//html/Amps/2001-10/msg00428.html (9,500 bytes)

I hadn't gotten that email yet when I sent the above question(s). It did explain that fairly well. I'm searching the archives to see if I can find Mr. Rauch's tale that you me; /archives//html/Amps/2001-10/msg00431.html (9,344 bytes)
5. [AMPS] Distortion, amp design, and 813s (newbie alert!!) (score: 1): Author: kd5izi_tech@yahoo.com (Randall DuCharme); Date: Wed, 19 Sep 2001 10:17:57 -0700 (PDT); Greetings, The latest IMD thread has been very educational and inspiring. Thank you all! My questions are probably old ones but being new to the sport..... :-) Anyway I'm about to embark on my first; /archives//html/Amps/2001-09/msg00347.html (9,295 bytes)

(score: 1): Author: kd5izi_tech@yahoo.com (Randall DuCharme); Date: Wed, 19 Sep 2001 16:43:31 -0700 (PDT); How so.... aside from the extra complexity of bandswitching, load matching, balancing, etc?? Interesting. Is this a characteristic of the tube or one of poor design or of poor loading/driving practic; /archives//html/Amps/2001-09/msg00351.html (9,675 bytes)
