At TEK we were never told of any specific failure mode,just that the ICs 
were first in short-supply,then "internal use only",then not 
available;supply depleted.

ISTR it was a bad production run,and the high failure rate was not known 
until the ICO/Hybrid manufacturing unit was sold to Maxim and no changes 
were able to be made.

But a HS would not do any harm.
(as long as it does NOT contact the cabinet.)
