To be fair it only affects the older ones with the RIFA MP2? caps. New Schaffner filters are as good quality as it gets.

Do you, or anybody else know, from which datecode on these Schaffner filters have been improved?

Re Schaffners, some other blogg postees have commented that it seems to be a problem of
-old equipment (old IEC filter)
- humid environment
- infrequent use (build up moisture in cap)
- then switch on failure- quite quickly
Occurrence in NOS treated in a similar manner.
Looking for a replacement for some older HP gear, Schaffner seems to be one of the better brands. I plan to think of them like electrolytics, need an eye and not infrequent replacement.
