Elliot vented 2A3PP line, is also very simple, the key is the quality of the output of cattle. Use 3KPP output cattle, fixed bias (a 62V), output power 15W. 2A3PP suited for th

e promotion of the sensitivity of 88dB or more speakers, electrical components or select a single Western Extension, Sibi electrolytic capacitors, AB carbon resistor, is still the star grounded. Power connection, after rectification of the first stage with a capacitance of 1O Sibi oil capacitors, the capacitors used in the tube rectifier circuit effect is significant, can protect the rectifier guts, but also to ensure sound. Welding installation weld pressure and also the first filament loop and then welded the signal path on the line. Check whether the normal operating point at all levels, the ground levels are correct, and finally connect Bu 2A3SE pre-GP18, audition this time with a KEF 1O5 sE-RIES-2 monitors. Tsai is also broadcast old songs and other tracks, but it is completely different feel: the sound field through the wall through the three-dimensional wall not heard before, even KEF that a 1O5 notoriously difficult to control bass are tame ease, and rhythmic unambiguously. Like force of the sound field is very beautiful, broadcast Tony Nine actually have enough control, people can not believe it is a 15w after the 2A3 level in promoting a 1O5 KEF speakers, you know a lot of people with a 200W stone push it machines well, 2A3PP really worth a good DIY machine!
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
