Filter Cap Ground Connection Wilcox Gay 1J10

:: This set has some White "chalky-like" regular caps. Are these ceramic caps? They resemble about a 1 inch stubby white crayon. Stamped in black there is for instance a 220K 100 mmf
::As well as larger caps like .005 and a dual .0001 mfd.
::
::Three of the caps have a wire wound around one end
::a couple of times. I have to replace C11 (470K .005) like this.
::Should I just wind the wire around so it does the
::same thing on the new replacement?
::
::Do the schematic drawings for the negative filter cap ends denote anything different with it's forked like end to the ground symbol?
:
:Bob, that's one of the symbols used for wet electrolytics. The individual values for the lugs are differentiated by the small triangle, square, and part circle symbols. These smaller symbols will be near the lugs as well on the outside with value and voltage. I don't know if that capacitor symbol was ever adopted by EIA but some did use it...yours makes point.
:Bill

Sorry, question on does it denote anything...I speculate the symbol was developed somewhat as representative of the construction of capacitor, the anode and cathode.
