IWISTAO Finished Tube FM Stereo Radio Tuner Plus 6P1 Tube Amplifier Stainless Steel Chassis Black Aluminum Panel HIFI Audio AC 220V
Model No: WVTR-FM09-RJ
This unit is a typical superheterodyne radio. It adopts a whole circuit board design that include high frequency receiving, intermediate frequency amplification, limiting, frequency discrimination, stereo decoding, preamplification, etc. The output is stereo signal. It can be connected with various types of tube power amplifiers, active speakers, stereo equalization amplifiers and other equipments.
The specific circuit configuration is as below, high frequency receiving adopts double triode 6N3 for high frequency amplification and mixer amplification, and double triode 6N1 for local oscillation. The IF amplification uses a two-stage pentode 6K4, two-stage limiting, and a pentode 6J4. Phase frequency discrimination, stereo decoding uses TA7343, the decoded audio signal is switched to the double triode 6N2, and then the signal output to preamplification with a 5 times gain, and finally the output audio signal is sent to a double triode 6N2 to push two 6P1 The power amplifier and restores the sound through the speaker.
Features
1. High receiving sensitivity, using vacuum tube to receive FM signal, with a strong sense of nostalgia, sweet and mellow sound.
2. Use potentiometer and varactor diode tuning, it solves the trouble to use an air capacitor to make the cable drawing system. And uses a digital tube to display the receiving frequency.
3. Use a vacuum tube 6E2 to display the received signal strength, increasing visibility and viewing.
4. Its Chassis aluminum is made of alloy panel plus stainless-steel chassis, light weight. The panel is CNC-processed and oxidized, and the outer casing is made of stainless steel bent and welded.
5. Matched a mesh cover to avoid accidental burns and electric shock.
6. Its knobs are also processed by CNC machining, which is high-end atmosphere.
7. Designed as whole circuit board that is made of 2mm thick PCB, which increases the mechanical strength and is not easy to damage.
8. The power amplification section is separately installed for easy maintenance.
