http://goldprivacy.com Articles And Thesises About Audio Thu, 07 Aug 2008 13:02:15 +0000 http://backend.userland.com/rss092 en This article covers commonly used vacuum tube amplifier configurations with emphasis on types used in veteran radios and veteran communication equipment. The article discusses each configuration first at a fairly elementary level, aimed at readers with limited technical insight or readers who just want an overview of the amplifier type. ... http://goldprivacy.com/vacuum-tube-amplifiers/ A special effects are usually gained from an effects pedal. The pedal is separate from your amp and needs to be plugged in and used as a separate tool. While this can be a cheaper option, buying an amp with the effects built in can be simpler and better quality ... http://goldprivacy.com/guitar-amps/ Single-ended tube amplifier with two 1626 tubes in parallel per channel Six JAN (joined army navy) tubes, after some 40 years of rest, finally make music… I started this project with the idea to build a simple single-ended tube amplifier. I didn't have any experience with the construction of tube amps so ... http://goldprivacy.com/darling-se-amplifier/ When you're suffering the itch to improve your system but can't find the money, a possible solution is to spend some time fiddling with your turntable. (If you've gone CD-only, you're out of luck here.) Like everything else, the delicate mechanics of turntables are subject to the laws of entropy ... http://goldprivacy.com/turntable-system/ I built a 2A3 SE (Single Ended) amp a long time ago. I built it because I wanted to see what all the fuss was about, so I built it using the parts I had. I had received a pair of Chinese 2A3 in return for some help with a ... http://goldprivacy.com/2a3-se-amp/ Here's a 2A3 SE amplifier that I had just finished yesterday. I used a pair of EH's 2A3 gold grid and a pair of RCA's 6SN7 for driver stage. The photo shown Chinese 6N8PJ( Chinese Military 6SN7) for testing. I use solid state rectifier and use 2 pcs of 100 ... http://goldprivacy.com/2a3-se-amplifier/ In Brief Single-Ended Triode (a.k.a SET) amplifier producing 1...1.5W into 8 ohm load. Uses two Russian deflector combo 6f5p tubes wired as triode. Introduction 6F5P is Russian TV deflection triode/pentode combo tube, somewhat like ECL85/6GV8. If the pentode section is connected in triode mode, the tube provides a great playground for experiments with ... http://goldprivacy.com/6f5p-se/ This is such an in depth subject that I will reserve my input to this component to more basic explanations and leave the permeability and make-up of core material, magnetic flux density, shunt capacitance/inductance, electromagnetic theory and the like to references. I will instead concentrate on the more basic functionality of output ... http://goldprivacy.com/transformers/ A SE transformer has to do two things in life... carry the unbalanced DC and have enough magnetic oomph to do the AC duties well. PP outputs (largely so) are relieved of the DC duties. As a very general approximation the SE transformer will be four times as large as ... http://goldprivacy.com/lafevre/ A common-cathode triode stage exibits an harmonic spectrum decreasing (in a monotonic way) with the frequency and the contribution furnished from even harmonics (particularly the second one) is preponderant. A similar pentode stage presents a wider spectrum and therefore a general increment in the THD values and a greater contribution ... http://goldprivacy.com/cascade-stages/
