Description
Warm tips:
1. NOT include M3 copper columns in the display pictures, if you want better display effects please prepare by yourself.
2. NOT include 12V power adapter, please prepare by yourself.
6E2 tube sound level meter indicator, with different dynamic display effects. Adopting 2pcs valve tubes, the green light feels soft and charming, with strong vintage feelings, very suitable for home/office/studio audio system to dynamically decorate your auditory feast.
Features:
1. Power supply.
Powered by DC 250V/100ma.
The filament voltage of 6E1 tube is 6.3V and filament current is 300ma.
The two filaments are powered in parallel by 6.3V, or in series by 12V.
2. Fluorescence height
The parameters of the two tubes are inconsistent due to the individual differences of the 6E2 tubes, so the fluorescence heights of the two tubes may be a little different. Therefore, two trimming resistors VR2 and VR4 are set on the driving board, used to adjust the fluorescence height of the left and right tubes to achieve Highly consistent fluorescence of the two tubes.
3. Socket 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)
Left and right terminal block serial number and description:
1. Connect the gate, (6E2 tube signal injection pin) to the socket 1st pin
3. Connect the cathode, pipe grounding foot, take the third leg of the socket
7. connected to the control grid, used to control the fluorescent height of the tube, the seventh base of the socket
8. connected to the anode, 6E2 tube power supply feet, take the 8th foot of the tube
Pins 4 and 5 of the socket are filament powered pins, the two filaments are powered in parallel by 6.3V, or in series by 12V.
The 100K position of the DIY kit welding resistance should be 120K.
