Two-way 6E2 tube cat-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 plate 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. Pcb
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 cat's 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
The sub-tube is connected.
Drive board adjustment method:
W1,W2 is input sensitivity adjustment, clockwise adjustment sensitivity enhancement, low volume
More responsive (precision multi-turn adjustable resistors can be adjusted by 10 turns).
W3, W4 is the screen opening amplitude adjustment, clockwise adjustment opening

amplitude becomes smaller and more conciliade
Close state (precision multi-turn adjustable resistance can be adjusted by 10 turns)
The finished cat's eye 6E2 tube holder is connected to the drive plate:
1 foot green line drive plate port 1.
2 foot red wire to drive plate port 2 (2,6,8 foot tube inside is connected)
3-foot black wire-to-drive plate port 3.
4, 5 feet are white wire filaments, the original wire pin or the blue line of the package C transformer.
7-foot blue line drive plate port 7,
9-foot yellow line drive plate port 9,
The 250V port is connected to 220 --- - 250V DC.
The ground end or horn ground wire is concentrated in the Ground contact.
INL, INR is the signal input, respectively, to the left and right red terminals of the horn port.
Operating voltage: 220-250V, 6mA, DC voltage one-group; 6. 3V, 0. 6A Group,
AC DC is available.
