|Tung-Sol DT-1704C 'Digivac' VFD Tube ||
|Written by AnubisTTP on 2006-10-15
The DT-1704C is an early seven segment VFD tube packaged in a narrow 9 pin envelope. Like other early VFD tubes, this device predates the inclusion of a control grid and therefore can not be multiplexed. This model of tube seems to be very failure prone; bent heater filaments and uneven or partially unlit segments are common. The pinouts of this tube are identical to the General Electric Y-1938 display shown here.
