Re: Schlumberger Solartron 7150 IEC inlet & filter
In my experience restoring/repairing test equipment, all Schaffner IEC line filters that are 15 or 20 years old have very poor reliability (even if they are "new old stock"). With some equipment it seems that all the Schaffner filters are failing. More comprehensive testing of the few units that appear to have survived shows these are actually also faulty.
Some Schaffner filters fail by exploding, others are less dramatic, and still others may appear fine but have actually failed. As mentioned they usually produce smoke, leak brown gunge, and emit a disgusting odour that lingers for days.
While the Schaffner filters in the photographs below are not the type discussed in this thread, the results of the failure are nevertheless typical. One hopes that with new stock the problems of Schaffner filters have been rectified. However, with knowledge of their history, and without any technical reassurance, I would not recommend their purchase.
