155-0152-01
The Tektronix 155-0152-01 (M152B) is a Tek-made geometry and focus correction circuit designed to appropriately predistort X and Y signals before they are applied to the deflection coils of a CRT, in such a way as to eliminate "pincushion" distortion. It also provides a signal to correct for spot de-focusing that occurs away from the screen's center.
