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... |
