Altec 1566A:Vacuum Tube Preamp & Direct Box Project
: There are all sorts of tube circuits, some of which actually deliver The Sound people associate with Vacuum Tubes. Did you know, for example, that asymmetrical distortion
generates even-order harmonics while symmetrical distortion produces odd-order harmonics? Neither vacuum tubes nor transistors are exclusively responsible for either type of distortion,
it’s really about circuit design. (added 4/02) |

Audio Amplifier Output Relay Delay: This is a simple circuit
which I built to one of my audio amplifier projects to control speaker output relay. The purpose of this circuit is to control relay which turns on speaker output relay in
audio amplifier. The idea of circuit is wait around 5 seconds after power up until speakers are switched to amplifiers output to avoid annoying "thump" sound from
speakers. Anor feature of this circuit is that is disconnects speaker immediately when power in amplifier is cut off, so avoiding sometimes nasty sounds when you turn
equipments off.... (added 11/05) |
