Now that you've seen them, test yourself.


Can you find the two silver mica caps in this build?

[lynessmy]

Yup...two of the dark brown is the one....
How about the brown colour one? Metallized Mylar?

Is Metallized Mylar and Mylar different?

A metallized cap is one where the metal "plates" have been deposited as a thin layer on the dielectric film. The old fashioned way is to just use a thin metal foil for the plates. The advantage of metallized caps is that they can usually make them much smaller. Some people prefer the sound of one over another.
The cool thing about foil caps is that you can make them yourself at home with aluminum foil and wax paper...... well, sorta.
