Description
Tips: If there is no basis for tube welding, it is recommended to buy a finished product.
TIP：Copper column does not include.The Video only for refer.6E2 Low voltage drive version Package:(Can choose Kits or Finished )1: DC-DC booster board: 1 (DC 12V boost to 250V adjustable)2: Dual 6E2 driver board: 13:6E2 tube: 24: Tube seat (with extension lead): 2Power supply: DC 12V (two tubes of filaments are connected in series and the booster board shares 12V power)The two-way 6E2 cat's eye tube drive, the tube base is connected with the main board by flying wire, the wiring is simple, the use is more convenient, and the new design of the board minimizes the space occupied by the machine.1, the audio input signal amplitude can be adjusted, VR1 and VR3 to change the input signal amplitude2. 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).3. 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 tubes4. 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)5, the base is made of universal small nine-legged tube ceramic tube seat front mounting hole distance 28mm, panel opening: 18mm6, PCBA wiring: ainR / ainL: left and right channel audio signal input G: ground 250V: (DC),Left and right terminal block serial number and description:1. Connect the gate, (6E2 tube signal injection pin) to the socket 1st pin3, connect the cathode, pipe grounding foot, take the third leg of the socket7, connected to the control grid, used to control the fluorescent height of the tube, the seventh base of the socket8, 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! Note2: The 100K position of the DIY kit welding resistance should be 120K.
