Indicator Module Spectrum Vacuum Driver Review

NEW two-way 6E2 magic eye tube audio level indicator driver kit, suitable for DIY enthusiasts or installed in your gallbladder power amplifier, PCB board can be fixed in any cabinet amplifier, connecting the tube seat with flying wire. NOTE: This product can only give people a visual sensory experience, it is not a power amplifier. Tips: Shipped items as the first main picture shows, and the other pictures are only for reference. Two 6E2 tube magic eye drive board: audio signal that enables the 6E2's screen column to follow the size and flashing, the screen glow area is proportional to the signal size, when no signal, the luminous area is the most small, strong signal. The upper and lower light bands expand from both ends to the center until they overlap, excitation in the alterging signal.The 6E2's green electric-eye screen changes with the signal, lifelike like a cat's eye. The circuit of this drive board adds a first-stage amplification circuit to the old circuit to improve Input sensitivity, input device impedance of 100K, reduces the shadow of the original circuit after access sound, the board is equipped with precision multi-turn adjustable resistance W1, W2, can adjust the input sensitivity, applicable a variety of signal options can be connected to the front-level audio signal output or the amplifier's horn output. The plate is equipped with 100K precision multi-turn adjustable resistance W3, W4, which can adjust the light band open and close scale,makes the left and right channels symmetrical at static time.This PCB board is a dual panel with a small form factor, reducing the required mounting space, easy to add to the existing equipment,installation use more flexible and convenient.Bile tube wire flying wire connection, so that the PCB board can be freely fixed position. Fly wire only need to connect the magic eye tube seat 1 foot (gate pole input), 2 feet (similar to anodes, 2, 6, 8 feet inside is connected can be connected feet.Tubes are different or slightly different), 3 (ground, cathode), 7 feet (similar to curtain gate adjustable light band open and close scale, 7, 9 at the bottom of the tube seat connected). The filament simply uses twisted pair wire from the other electric tube is connected .
