Hi All,
I have an all original Eight Ball Deluxe from 1981, it was missing a flipper and also had some blown SCR's on the lamp driver board.
Having transported it 1200 miles across Europe, sorted the above issues and replaced the diode across the knocker, I was amazed to have a fully operational pinball.
Now after several weeks of use, a new problem has cropped up. The "C lane", "6,14 drop target" and upper "left pop bumper" have become intermittant in their operation. (All three at the same time)
Looking at the schematic they seem to be on the same line to A4J2-I3. Can anybody tell me the best way to isolate and fix this rather annoying intermittant fault?
Thanks in advance.
