Ceramic Vs Paper In Oil Caps

I m not saying i like the orange drop better than the pio.

Ceramic vs paper in oil caps. They still have the kraft paper in oil construction like the vintage russians but these are hermetically sealed metal tubes with glass ends so the value will not drift over time. A cap lets the tone control roll off the treble response progressively warming the tone. The cheap ceramic caps are a little different story. The bumble bee caps were later replaced by the black beauties which contained a winding of aluminum foil and paper film along with oil and were printed with the specs.

Did i just buy some magic beans or the brooklyn bridge. Others are made out of mylar ceramic etc. These caps were filled with paper in a special oil inside of bakelite bodies with the original nema color codes printed on them this is how many resistors are still printed. Truth be told i don t like one more than the other because i can t tell a difference.

Paper in oil or pio caps are just one variety of capacitor. Briefly a capacitor in the context of musical electronics consists of two plates of conducting metal separated by an insulating layer called a dielectric for example if you took two rolls of aluminum foil and unrolled them sandwiching a layer of paper between that would make a capacitor. Capacitors are energy storage devices that filter the high frequencies.
