P1 AX84 Guitar tube Amplifier

Tube guitar amplifier

Making a guitar amplifier may be slightly different to make an audio amplifier because it is devoted to the instrument so that the frequency range is designed for guitar. Selection of the type usually consists of a guitar amplifier of this type of tube and solid state, although the selection is very large relative to its taste and budget dikantong
For the price this guitar amplifier guitar amplifier tubes dibanrol more expensive than the amplifier that is made of solid state, well why the price is more expensive but still sought after by connoisseurs of electric guitars sound particularly likely because dikhasilkan by an amplifier of this type is more striking and kicking hearts. Although the technology was seen absolete but the old-fashioned for this one is endless, until now many musicians, especially guitarists remained faithful to use the amp type in up to now
Due to expensive for a newbie is very difficult to obtain these types of amps, for that share a little experience in building an amp of this type, as already mentioned this technology is very long so it is not often found in new products but still only for connoisseurs of high end audio with the type of This amp is still a primary choice.
To make this amplifier is actually easier because the circuit is simple but it is necessary to use high voltage high caution. Basic knowledge of electronics becomes absolute, the right to read reference about tube technology into the entrance which is helpful to understand the use of tubes. Usually there is a specific naming for this example 12AX7 tubes, ef86, 6dj8, etc. el34.
The tube amplifier is actually working as anaoda and kathoda using the heater tdrjadi reinforcement. Named because the tube is formed from a hollow tube usually made of glass and ordinary incandescent bulb has properties that can drop suddenly when age or wear telahh time runs out. For working voltage required 2 teganngan keja want good ac dc voltage, ac voltage to be used to power the heater is biased About a 6.8 V. For high voltage although it could use a low voltage tube usually works on 150 V with small currents
It required power transformers yangsesuai depending on the class amplifier that we bua class A, B, AB sometimes need to receive training trfo weight, to output tube amplifier output transformer also used to meyesuaikan kohm impedance to the impedance of some speakers as common as 8,4,16 and so on. so totalized terapat usually at least 2 transformers and 2 pieces of tube
Examples of the output transformer and power transformer can be seen from Figure 1.
Examples of artificial transformer can be seen in figure 2.
As there is a section of such amplifiers pre amp, tone control, power ampnha tube likewise, do not forget the power supply for high voltage dc. We will try to discuss the perbagian, starting with the powersupply.
Divided from the power supply transformer voltage produced two high-voltage and voltage for the heater. High voltage into the swtich stand by that point to mengantur when we enter the high voltage to the tube. Usually when we first turn our amps of this type include turning on power to the heater voltage on the tube is marked with a turn on the tube, stand-by switch means bedinyalakan tube still has not given a high voltage so that the tube does not work at its operating temperature before it is done so that the lifespan of the tube more long time. rectifier or rectifier in the high voltage rectifier tubes can be performed by a diode rectifier or regular, which it surely will menbhasil different characters
usually every stage of reinforcement given a different voltage from the smallest to the largest preamp to power amp can be seen from the combination of resistor and capacitor filter for each teganagn. Usually at this stage 12AX7 tube is used in which there are actually two channels so that the signal 2 times.

Step 1 First Stop

This project based on P1 from AX84.com, this project are intermediate to people that never experience to build using tube (valve) but beginer for whom experiencing,
basic need you have know to read schematic. in AX84 very cooperative how to build so i recomend that yo try to read all the document first and continue to build this amps
