And not so modern parts. I've still got a few pounds of paper-oil
capacitors (lots of Rifas) from the 1980s. Picked them up as mixed NOS
priced about 25 cents per pound. About half are market with polarity
marks. I never understood why.
I used one recently to replace an ignition capacitor in a 40 year old
chainsaw (a Stihl 056). Works a treat.
