6E2 Cat's Eye Tube Audio Indicator Driver Board Fluorescent Tuning Instruction Circuit DC12V

DC12V 6E2 Cat's Eye Tube Audio Indicator Driver Board Fluorescent Tuning Instruction Circuit Product parameters Product Name: 6E2 Cat Eye Electronics Power supply: DC12V 1A Signal input: ≦0.775V Instructions for use 1. DC12 power supply. 2. The amplitude of the audio input signal can be adjusted by PR1 and PR2 to change the amplitude of the input signal. 3. The parameters of the two tubes are inconsistent due to the individual differences of the 6E2 tubes, and the fluorescence heights of the two tubes are not the same after lighting.Therefore, two trimming resistors PR3 and PR4 are set on the driver board to adjust the fluorescence height of the left and right tubes to achieve two The fluorescence of the tube is highly consistent. Precautions: 1. Please check whether the wiring is correct before powering on. 2. Don't touch the circuit board at will after it is connected. 3. The voltage of the direct power supply should not exceed 13V. Package Included:Driver board x1 Connection board x2 Connection line x2 6E2 tube X2
