Platine Dimension is 86mm x 60mm.
On list is a kit of magic eye tube 6E5C audio level indicator board. The tube illuminates as a charming indicator for all tube and vintage lovers. This board is designed to be matched with the output level of audio source, pre-amplifier and power amplifier with adjustable sensitivity. Each board can serve one audio channel.
The board requires a supply voltage of 170Vdc to 250Vdc 10mA , and filament voltage of 6Vac or 6Vdc at 350mA. This can be done by an appropriate transformer and simplistic rectifier circuitry.
When the input level is appropriately adjusted ( by the on-board potentiometer), the tube green opening will change with level. The maximum extent of the movement is within a quadrant ( or about 90 to 100 degree)as shown in the picture. The opening would not alter beyond the degree thus mentioned. Please do not expect the green light will move around the whole ring as in modern LED bars.
Each listing includes the bare board , a high quality ceramic base tube socket and all the components for the board the 6E5C tube.
Board Dimension is 86mm x 60mm.
