Digital Interface / Sound Card. 3.5 Line Out Cable. Vintage Vacuum Valve Tube FM Radio Wireless Stereo Audio Receiver Preamp. Not include Antenna, you need to prepare it by yourself. Superheterodyne radio adopts a whole circuit board design, including high frequency receiving, intermediate frequency amplification, amplitude limiting, frequency discrimination, stereo decoding, preamplifier and other circuits.
The output stereo signal can be matched with various tubes. Power amplifiers, active speakers, stereo equalization amplifiers and more. The high frequency receiving adopts double triode 6N3 for high frequency amplification and mixer amplification, and the double triode 6N1 makes oscillation.
The intermediate frequency amplification uses two-stage pentode 6K4, and the two-stage amplitude limiting uses a pentode 6J4. Phase frequency discrimination, stereo decoding uses TA7343, the decoded audio signal is switched by the switch to the double triode 6N2 for 5 times preamplification, and then the audio signal is output.Using vacuum tube to receive the FM signal which has a strong sense of nostalgia, the sound is more sweet and mellow. Using potentiometer and varactor diode tuning, the digital tube displays the receiving frequency, using 6E2 to display the received signal strength, increasing visibility and viewing. Exquisite appearance design, high receiving sensitivity. The panel and the knob is CNC-processed and oxidized, and the outer casing is made of stainless steel bent and welded, which brings different high-end texture.
The whole circuit board is made of 2mm thick PCB, which increases the mechanical strength and not easy to damage. The mesh cover design can prevent children from accidentally touching burns and electric shock.
