1. [AMPS] A "no tune" amplifier output section/operation question. (score: 1): Author: nospam4me@juno.com (Skip S Isaham); Date: Mon, 06 Apr 1998 23:31:26 EDT; Hello again, I have a question about the No Tune type of amplifiers that are/were offered for sale to amateurs through the years. Would one of you take a moment to mention the makeup and consideratio; /archives//html/Amps/1998-04/msg00045.html (9,007 bytes)
2. [AMPS] A "no tune" amplifier output section/operation question. (score: 1): Author: ggeurts@amp.com (Geurts, Gerard); Date: Tue, 7 Apr 1998 09:12:50 +0100; Skip, There is only one way I know to make a no-tune tube amplifier, and that is by making a so called distributed amplifier. In this configuration a large number of tubes, normally tetrodes, are con; /archives//html/Amps/1998-04/msg00046.html (11,293 bytes)

"No tune" vacuum tube power amplifiers: All the practical ones (i.e., NOT distributed amps with 8++ tubes and efficiency <30%) are really band-pass, not broadband. Most hams have; /archives//html/Amps/1998-04/msg00053.html (12,807 bytes)

As I said before, the effect of 20 pF at 2500 Ohms is a bit bigger than 5 pF at 5 Ohms. It is this high impedance / high capacitance combination that makes broa; /archives//html/Amps/1998-04/msg00060.html (7,984 bytes)
