Sleeves, focusing systems of reading guns, correcting coil from 0949-th CRT are visible. Also next to the focusing system is a piece of copper foil, which served as a electrostatic shield for reading gun deflection system. In the photo there is no similar screen from the 0698th pipe, because when it was dismantled, it tore into small pieces. By the way, the correcting coil is made by the well-known firm Syntronic instrumentsinc. Coil type C16165-2 99409-93-06. As for the features of the focusing systems of reading guns. I do not know why, but the focus assembly from the 0949 pipe in the mouth, which covers the average diameter of the cylindrical part of the CRT, installed a garland of seven red LEDs, glowing inside a translucent tube of silicone rubber. When they are turned on, it turns out that they illuminate the first widening of the bulb from the reading gun, and, as a consequence, the target from the side of the writing half is illuminated by diffuse light. "Sausage" with a garland is clearly visible on the left sidebar. I was not even too lazy and took a picture of this sausage included - accordingly, it is on the right. Perhaps this is some kind of tricky calibration system. Honestly, I do not remember if it was in 0698 ... The hole into which the wire from the LEDs is released is present - maybe a year and a half ago I just pulled them out of my mind and then lost...
