[BC] Harris SX-1A NRSC woes...

[Milton R. Holladay Jr.]

I haven't seen any that slosh, but have found some that klunk, in a DX-10.
All blue, IIRC. I suspect that klunking is the second stage of failure after
the sloshing has all dried up and gone unnoticed in instances where there
was no obvious equipment failure during the sloshing stage.
Age is not a reliable way to judge, as many older ones are just fine, like
those in a ~1980 AMPFET-10.
It appears as if the mfgs--especially Sprague--lost the recipe for making
them correctly, and at different times for different types ............
