Description:
Note: This is a DIY kit, it need buyer to assemble it. thank you.
6E2A level indicating board, adding a first-level amplifying circuit on the basis of common circuit, improving sensitivity, input impedance up to 200K, reducing the influence on the original circuit after access, potentiometer on the board, can adjust input power Flat, suitable for a variety of signal level display, can be connected to the audio signal output of the front stage or the speaker output of the power amplifier.
Features:
1. A 200K potentiometer is added to the PCB to adjust the opening and closing scale of the optical tape to facilitate the symmetry of the left and right channels.
2. A blue highlight LED is mounted under the 6E2 tube for a more beautiful and beautiful effect.
3. The 6E2 level PCB board is a double panel, and the components can be mounted on both sides for more flexible and convenient installation.
Dimensions: 7.3 × 3.8CM
Working voltage: 180V-250V 8mA, 6.3V 0.3A each group. 180V-250V is DC voltage, AC /DC6.3V.
Installation instructions:
The two terminals of 6.3V next to the socket can be connected to AC 6.3V or DC 6.3V. Connect DC 6.3V to pay attention to positive and negative, otherwise the LED does not light.
HV and 0V are respectively connected to high voltage, 150V-250V, and must be DC. The HV is connected to the power supply. 0V is grounded.
IN and ground symbol, which is the input signal terminal, IN is connected to the signal hot end, the middle terminal of the lotus terminal, and the red terminal of the speaker. Ground symbol connected to the cold end of the signal
Package included:
1 x 6E2 Tube + Driver Board
