The Tektronix T5192 is a CRT used in the 3 GHz version of the Type 519, the 519C. Typical vertical deflection sensitivity is 210 V/cm (versus the ~10 V/cm of the original 519), and maximum sweep speed is 1 ns/cm.
The T5191 and T5192 have completely different deflection structures.
According to February 1, 1963 TekWeek, Tek started taking orders in February 1963 for a CRT and modification kit, at $1500.
