Air conditioner
Made by Armstrong Air Conditioning now Allied AIR, Bellevue, Ohio
Unable to find HP of compressor, running amps 11.9, Lock rotor amp 59, Volts 208-230, my calculations 3.5 HP
Fan motor A. O. Smith 1/5 HP

I am unable to read markings on capacitor due to corrosion and poor markings. There does appear to be the word "YORK", as in York Air conditioner. All else to faint to read.

Can any one tell me (or calculate) what size this capacitor might be.
This is a compressor/fan start capacitor. Physical size, 2" diameter, 4" high.
