[time-nuts] HP53131 Power Supply shortened

[Marek Doršic]

Hello,

    while taking a measurement my HP53131a counter sparked and became quiet. After tear down I found both 3A/240V fuses in the PSU burnt. Before pluging a new set of fuses, is there a knowledge of a common problem that couses a shortcircuit at the HV side?

The counter has also a spilage at the bottom side of the mainboard, but as it is same as in Gerry Sweeney's youtube video (HP 53131A Teardown and Spillage Clean-Up <https://www.youtube.com/watch?v=czCLXrUPX0o>) and his counter still works I assume it is not related. Is it a good practice to get it cleaned?
