Vacuum Tube FM Radio Vintage Audio Valve Stereo Receiver DIY/ 6N3/6N1/6K4/6J4

Vacuum Tube FM Radio Vintage Audio Valve Stereo Receiver DIY/ 6N3/6N1/6K4/6J4. Circuit structure, design principle. This machine belongs to the typical super-external difference radio, using a circuit board design form, including high-frequency reception, mid-frequency amplification, limiting, frequency discrimination, stereo decoding, preamplification and other circuits, the output is a stereo signal, which can be connected to a variety of types of tube power amplifiers, active speakers, stereo equalization amplifiers and other equipment. Specific circuit configuration is as follows: high-frequency reception using dual triode 6N3 to do high-frequency amplification and mixer amplification, dual triode 6N1 to do the local oscillation. Mid-frequency amplification using two-stage pentode 6K4, two-stage limiter, using pentode 6J4, phase frequency identification, stereo decoding using TA7343 (the latest version has been changed to LA3401), the decoded audio signals are switched to double triode 6N2 after conversion switch for 5 times the preamplification, the output of audio signals. Second, the machine highlights This machine has a light weight, high reception sensitivity, the use of electronic tubes to receive FM signals, with a strong sense of nostalgia, the sound sweet, mellow, the use of potentiometers and varactor diode tuning, to solve the need to use the air capacitor to do the trouble of pulling the line system, while the use of digital tubes to display the receiving frequency, the use of 6E2 to display the strength of the received signal to increase the visibility, the ornamental nature. The use of mesh cover design, you can avoid the children at home accidentally touch the scalding. The panel is oxidized by CNC machining, and the shell is made of stainless steel bending and welding. The knob is also CNC processed and polished, high-end atmosphere, the whole machine circuit board is made of 2mm thick PCB, increasing the mechanical strength, not easy to damage. Third, the machine parameters: Receiving band range: FM87-108MHz. Power supply voltage: 110V/220V Number of channels: 2, stereo. Machine power consumption: about 100W. Net weight: about 24Kg Receiving form: super-aberrant type. Four, the machine important components Power transformer, electronic tube, high-voltage filter capacitors, tuning resonance inductor, varactor diode, etc. Please leave note for your special request e. Please do NOT leave negative or neutral feedback without any contact. We care about our valued buyers, if you have any questions, our Customer Service staffs will be very glad to help you.

NEW Vacuum Tube FM Radio Vintage Audio Valve Stereo Receiver DIY/ transformers. This machine is not designed shell, enthusiasts need to use their own imagination to design their own shell. Due to the air four. Electron tube are not new production, are brand new inventory goods, please mind the friends detour. A circuit structure, working principle. This machine belongs to the typical super-aberrant radio head, high sensitivity, using electronic tubes to receive FM signals, with a strong sense of nostalgia, the sound sweet, mellow, and. The use of quadruple air capacitor tuning, is a lot of older people’s youthful feelings, the entire circuit board is made of 2mm thick PCB, increasing the mechanical strength, not easily. The entire circuit board is made of 2mm thick PCB, increasing mechanical strength and not easy to be damaged. This machine adopts a whole circuit board design design form, including high-frequency receiving, frequency conversion, IF amplification, limiting, frequency identification, stereo decoding, buffer amplification circuit, the output is a stereo amplifier. Large circuit, the output is stereo signal, can be connected to various types of tube power amplifiers, active speakers, stereo equalization amplifier and other equipment. The specific circuit configuration is as follows: high-frequency reception using dual transistor 6N3 to do high-frequency amplification and mixer amplification, dual transistor 6N1 to do the local oscillation. Mid-frequency amplification using two. The mid-frequency amplifier adopts two-stage pentode 6K4, and the limiter and frequency discriminator adopts pentode 6J4. The stereo decoding is done by LA3401, and the decoded audio signal is fed into the double triode 6N 2 for 5x amplification. After decoding, the audio signal is sent to dual triode 6N 2 for 5 times preamplification, and the stereo audio signal is output through dual RCA terminals. The quality of this machine components are carefully selected out, especially the electric. Decoder capacitors are imported black diamond or South Korea’s brand, have been tested by the voltage tester, we can rest assured that the use. Second, the use of steps. Of course, if you want to receive more radio signals, you must use an external omni-directional outdoor antenna, impedance is 75? . Please make sure that the wiring is correct, can not be wrong! From left to right wiring order is as follows. Brown – brown (11V); green – green (230-230V); blue – blue 6.3V; black – white. The two yellow (6.3V) wires are left unconnected and insulated by wrapping them in tape, so as not to short them out. The remaining two red are power cords, connected to the socket, this machine uses 220V. 3? Use RCA audio connecting cable to connect the audio output terminal of this machine with the audio input terminal of your home amplifier. 4? Turn on the power switch, the indicator light will be on, wait for about 20 seconds and then you can listen to the radio station. Rotate the tuning knob, you can select different radio signals. 5, the use of the process should be installed in the circuit board in their own design inside the shell, and the machine from the ground to have the appropriate height, remember to account for the age of children are not allowed to touch the electronic tubes and other components of the machine. Remember to explain not to allow young children to touch the machine tubes and other components, so as not to cause safety accidents! Third, the use of the process of possible problems and solutions. 1, the machine does not work, check whether the socket power? 2, the sound is small, murmur, check whether the antenna is bad? 3, there is a periodic murmur, check whether the machine around the high-frequency equipment in the work produced by the interference? Please leave note for your special request e. Please do NOT leave negative or neutral feedback without any contact.
