|
| I am trying to repair an old scope BK 1431 and I could sure use a good
schematic, a repair manual would be even better! Any help would me very welcome. The unit has no trace , no horizontal sweep at all and a dot shows on the tube but it fades away. I have replaced most of the capacitors and many resistors all the transistors test good and I have resoldered all the boards. I could use some help. . THANKS FOR INPUT! |
