Hi Refugee,
Thanks for drawing our attention to the AVNET electronic component date-code identification spread sheets
http://www.avnet-logistics.eu/servic...ate-codes.html
These are a valuable resource for those interpreting the markings on older components.
I suspect that waiting for a paper-dielectric capacitor to swell up is slower that watching paint dry! No doubt it depends on the humidity, so Rifas may last longer in the desert.
