T5611

The Tektronix T5611 (P/N 154-0531-00, 154-0531-01, 154-0531-02, 154-0531-03, 154-0613-00, 154-0613-01, 154-0613-02, 154-0613-03, 154-0614-00, 154-0614-01, 154-0614-02, 154-0614-03) is a ceramic CRT used in the 561A, 561B, 567 and 568.

There are three part numbers, differences being tube base and graticule.

T5611 with B14-38 base are replacements of the T5032 glass CRTs.
T5611 with special base are used in the 561B.

Specifications

Vertical deflection sensitivity is about 19.5 V/div. Horizontal deflection sensitivity is about 18.5 V/div.
