1. [AMPS] 3CX800 Load impedance (score: 1): Author: soeren_pedersen@chartec.dk (Chartec Laboratories A/S); Date: Wed, 1 Apr 1998 09:31:58 +0200; I am re-building an Advanced Radio Devices amplifier with 3 x 3CX800. The amplifier is designed to run on 4 fixed frequencies, thus the PI-L tank circuit and possibly the input circuit needs to be re; /archives//html/Amps/1998-04/msg00000.html (7,803 bytes)
2. [AMPS] Parasitics, AL-1500 (score: 1): Author: soeren_pedersen@chartec.dk (Chartec Laboratories A/S); Date: Wed, 29 Apr 1998 10:37:47 +0200; Hi all I have previously posted a mail to this reflector concerning poor efficiency of an Ameritron AL1500 amp. (8877), But after all discussions on parasitics I decided to make some additional measu; /archives//html/Amps/1998-04/msg00325.html (9,844 bytes)

Is damping the cathode with 10R/30pf equally as good as eg. 10R; /archives//html/Amps/1998-04/msg00340.html (7,742 bytes)
4. [AMPS] AL-1500, poor efficiency (score: 1): Author: soeren_pedersen@chartec.dk (Chartec Laboratories A/S); Date: Wed, 4 Feb 1998 17:30:02 +0100; I have an new AL-1500 amplifier which doesn't perform very good on 14 and 21MHz. Especially on 14MHz the efficiency is low. I have already asked Ameritron to get their opinion, but they just say that; /archives//html/Amps/1998-02/msg00010.html (9,173 bytes)
