    Simple Electronic Tube Model Removal ----- Vacuum Tube FM Radio

     

    Simple Electronic Tube Flower Radio, Vacuum Tube FM Radio Keywords: Simple electronic tube frequency frequency radio Simple electronic tube frequency frequency radio The power amplifier made by electronic tube is more charming, and the digital sound source is more charming. Due to the high quality sound source of FM broadcast and TV (sound), many tube enthusiasts have begun to have a strong interest in the tube radio, according to this author. Try, now the frequency modulated broadcast music channel, use the electronic pipe radio radio to receive the reduction music signal, and then play music with the electronic pipe audio amplifier. The sound quality tone is more than the brocade, which is God! Since FM broadcast (TV sound) works in a super high frequency range, under amateur production conditions, if the over-extra differential circuit, the circuit is complicated, the device is difficult, the author uses the method of ultra-regenerative reception, the circuit is simple, easy to make, The production will now be briefly described below. 1. Component formulation The motor circuit is shown in the figure, is a self-destroyable hyperbupler receiver circuit. Since most channel frequencies operate in the range of 88MHz to 108MHz, the Shanghai literary channel (intermediate frequency is 96.8MHz) is the reference point, the L2 uses φ2mm silver-plated copper wire, and the outer diameter φ15mm mold is wound with a loop spacing of 2mm to bypass 5. For L1 (φ2mm silver plated copper wire in the L2 outer casing, the distance between the circles is 2mm. The distance between the two coils is about 2mm to 3 mm. High-frequency blocking circle with φ0.32mm enamel line, The diameter 10mm paper tube is divided into 150 horses, and the antenna can be used for one meter long mock. The electronic tube is used for J-level 6k3p or 6k4, but also use 6J1, but its gain stability is not 6K3P. 6k4 (change μ tube). Variable capacitors have better finished products, without finished productive tutorial removal double variable variable capacitor restructuring, the method is to remove partial cartridges and fixing. Its capacity and film relationship is: the dielectric tablet has a capacitance of 20 pf, and the two-moving sheet holder is 47 pF, and the three-wheeled two-fixed piece capacity is 100 pF, and the specific use value is determined according to the received frequency. 2. Assembly debugging Since the FM part works in the ultra-high frequency state, this part of the component should be mounted on the organic glass plate or plastic plate, the coil mount should be 10mm to 15mm from the plate, the contact is firm, to prevent high frequency machine, and each component should be as compact Install appropriate position near the pipe to reduce the impact of distributed capacitance and leakage, facilitate debugging. This receiver is relatively simple. After the inspection is correct, turn on the power, adjust the power supply voltage control potentiometer W to the appropriate position, will hear the superscript of the slings, and adjust the variable capacitor C and regulate The coil L (stretching or compression) can receive a broadcast, at which time the hyper-regenerative noise is pressed, the electron pipe 6K3P gate resistance and the capacitance are adjusted to the appropriate value, and finally adjust the power supply voltage control potentiometer W, make the sound clearer And loud. At this time, the entire adjustment process is repeated, so that the sound quality is more pleasant.
