General Electric Y4075 VFD Display  
Written by AnubisTTP on 2010-04-24  


The rather hard to find Y-4075 display tube is the smaller cousin to the General Electric Y-1938 display shown above. Like the Y-1938, this tube is constructed using a series of phosphor coated tiles that are arranged in a seven segment pattern with decimal point. This is a very early VFD part number, and like other early tubes it lacks a control grid, making it nearly impossible to multiplex.

The example shown here was actually repackaged in an Archer blister pack for sale at a Radio Shack retail store. The mind boggles at the thought of a time when Radio Shack sold things other than batteries and bottomless piles of tawdry consumer goods.

It is hard to imagine a time when Radio Shack sold display tubes instead of bottomless piles of cheaply made cellphones.
