I`m searching the manual and schematic of the hung chang 5502 20Mhz dual trace oscilloscope.
I bought it very cheap but it has some problems, There is a segment of the board that manages the high voltage that is forming arches, it was repaired for another person. it seems to have had, from factory, some type of silicone , which was removed. what can I use to prevent the formation of arches?. I `ve remove the track that could have carbon traces but now with a wire the problem still occur. I thought putting varnish, even I have silicone as well.
