Hi All,
I also bought 41800A probe from ebay, the tip was broken but luckily the broken piece was with unit and I glued it together. the probe looks brand new but it did not worked.
So I start debugging and found that the power supplies of -7 and +9V is not correct on probe, I am reading -7V and +3V, has anybody faced same issue and fixed it? it would be really helpful. I did not find any schematic either.
Regard,
