David,

It isn't unusual to find a few  bad input circuit capacitors 
along with some failed output circuit caps. I've never 
noticed any other amplifier series that had so many small 
cap failures as the factor capacitors in the FL2100 series, 
even when the caps are well oversized.

I think the capacitors in the FL2100's are really 
mislabeled. They should be called crapacitors, not 
capacitors.
