1. Problem:
Solution:
In VIDEO EXT operating mode
- the pack porche of the sync pulse is distorted and
- the working point of transistor 317 is not okay.
- Transistor 317, BC 338, video input amplifier, unit 10 is replaced by BC 337-16,
5322 130 41095 from instruments L 0 18 ... onwards.
- Resistor 730 is paralled by a resistor 56K2.
2. Problem: IC 351 on unit 3, TCA 240, was sometimes not working properly.
Solution:
Alteration of resistor 604 from 825R to 715R, already inserted from L 0 13 ... onwards.
3. Problem: Diode BA 244, items 402, 404, 406 on unit 2 is not available anymore.
Solution:
Replaced by diode BA 482, 5322 130 34955, already inserted from L 0 17 ... onwards
4. Problem:
Solution:
The small knobs 5322 414 30027 for memostat, pie-selection unit, can sometimes be damaged.
Please operate the knobs only by hands or by cross-slotted screw-driver.
Don't operate with normal screw driver.
