T5470

The Tektronix T5470 is a 5 inch electrostatic deflection CRT used in the 543B, 544, 545B, 546, and 547.

It has an aluminized round flat face with 6 cm of usable vertical scan, and a helical post-accelerator. The entire envelope of 154-0478-xx is made of glass. Newer T5471 has envelope of ceramic. This variant has other numbers. It is called: 154-0568-xx

The T5470 has a specified dot size of 0.004", quite a bit tighter than the dot on higher-bandwidth CRTs that use an expansion mesh.

The 519 has a very different CRT, but the same specified dot size as the 154-0478-00.
