Digital Interface / Sound Card. 3.5 Line Out Cable. Vintage Vacuum Tube FM Radio Receiver Wireless Stereo Audio Amplifier Speaker. 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 to the double triode 6N2 through the transfer switch for 5 times preamplification and then output the audio signal t.
The 6P1 power amplifier pushed by a double triode 6N2, and the sound is restored through the speaker. Using vacuum tube to receive the FM signal which has a strong sense of nostalgia, the sound is more sweet and mellow. And the power amplification section is separately installed for easy maintenance. 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. Shell Material: aluminum alloy + stainless steel. Working Voltage: 110V(115V) /220V(230V).
