Description
6E2 Electronic Tube Indicator Kit High Voltage Power Supply Finished Kit Dual Channel Level Indicator Amplifier
Description:
- The audio input signal amplitude can be adjusted through VR1 and VR3.
- This board is not a preamplifier and has no power amplification. It only uses the way of fluorescent column to show the change of the amplitude of the audio signal, so that the audio signal is changed from auditory to visual (visual effect).
- The parameters of the two tubes are inconsistent due to the individual differences of the 6E2 tubes. After the lighting, the fluorescence heights of the two tubes are not the same. Therefore, two trimming resistors are set on the driving board, and VR2 and VR4 are used to adjust the fluorescence height of the left and right tubes to achieve Highly consistent fluorescence of the two tubes
- Pipe connection: The extension of the socket pin has been soldered out, and it is connected to the corresponding terminal number of the driver board according to the color of the lead wire (the delivery is accompanied by a wiring instruction)
- The base is made of universal small nine-legged tube ceramic tube seat front mounting hole distance 28mm, panel opening: 18mm
- PCBA wiring: ainR / ainL: left and right channel audio signal input
G: Ground
250V: DC
Left and right terminal block serial number and description:
- Connect the gate, (6E2 tube signal injection pin) to the socket 1st pin
- Connect the cathode, pipe grounding foot, take the third leg of the socket
- Connected to the control grid, used to control the fluorescent height of the tube, the seventh base of the socket
- Connected to the anode, 6E2 tube power supply feet, take the 8th foot of the tube
- Pins 4 and 5 of the header are filament supply pins (6.3V supply)
Note:
- The two tubes are connected in parallel to the 6.3V power supply.
- Two tubes of filaments are connected in series to take 12V power supply.
Package Included: (not include power supply board)
- 1 x Dual Channel 6E2 Driver Board
- 2 x 6E2 Electronic Tube
- 2 x Tube Base (with prolonged cables)
