Dynaco 6n2 6p14 Tube Amplifier Push-pull Line Stereo Power Amplifier Board 10W

Dynaco 6N2+6P14 tube amplifier push-pull line stereo power amplifier board

Product descrtion:

The famous American audio Dynaco tube amplifier is famous, and there is no one who doesn't know about it.

Dynaco lineage line 6P14, 6N2 tube amplifies inverted push-pull output, pushes 6P14 tube, 6 tubes are designed on the board for easy installation. Dynaco circuit is claic and cleverly designed. The 6N2 tube has two roles, it is both a voltage amplification and an automatic balance type inverter. The 8.2K resistor is the finishing touch. This resistor is not only a 6N2 cathode bias resistor, but also an inverted output secry. The tail of the phase level is also the loop negative feedback resistor at the same time! It saves parts and reduces the additional noise and distortion of parts. The power stage adopts a standard structure, the output power can reach 10W and the sound quality is superb! The following drawings are for reference only, the board is improved, and the markings on the board shall prevail! ! ! ! !

The amplifier board needs to be externally preed with a power supply and a , and the power supply is filtered by CRC. The S/N of the whole machine can be as high as -107db A weighting (absolute residual noise voltage 160uV). Such a low noise floor is basically only when the ears are close to the speaker. A little bit of noise. If the inductance filter is used, it will be the icing on the cake.

Exquisite FR4 double-sided gla fiber board, board size 148×91mm, board thickne 2mm. Parameter descrtions such as resistance, capacitance, voltage, and ports are marked on the board. The circuit performance is excellent, the wiring is reasonable, and the circuit is quiet. As long as the wiring is correct, a one-time succe is a shortcut to succe. Component foot pitch, base foot pitch, foot hole size, etc. are designed reasonably, suitable for large and small power resistors and capacitors. The electronic tube holders are designed for dual purposes, and the resistance and capacitance components can be aembled and welded on both sides. The tube sockets are designed with round and flat feet. The flat-foot holes are easier to solder than round-foot holes and do not leak tin, and are suitable for use in various electronic tube DIY circuits. Aemble sier-plated ceramic sockets, domestic precision five-ring metal film resistors, Nikon, Ruby and other electrolytic components, and German WIMA Weimar capacitor cro-connect components. The RC element has double-sided characters, which can be aembled on both sides, and the tube can be exposed for installation. Note: The pe socket should be aembled according to the characters, not reversed. The port identification on the board is detailed, and the input, output, feedback, power supply, output , cathode feedback wiring port, filament, etc. are marked in detail, and the aembly wiring is simple and not complicated.

Note:

P1 and P3 on the board are the upper tube, and P2 and P4 are the lower tube. The volume potentiometer and power supply are not on the board and need to be aembled separately. The secry pole of the output must be grounded, and the phase of the output must not be connected wrongly.

Supplementary descrtion of the circuit:

The large loop negative feedback resistor is connected to the speaker output terminal, and the speaker output terminal 0 must be grounded.

The output mode of this line is standard connection, not three-stage connection.

For suppreing and eliminating the hum, you can add a balancing resistor at the filament, or try to ground one end of the filament.

Affirm:

The components on the finished board are different due to different aembly batches. The types, brands, models, specifications and parameters of some components will be slightly different. The components and parameters aembled on the received board shall prevail! Some components on the circuit board are disaembled products, and the finished boards are tested and sold normally.
