Hi!

I'm yet to build any effects pedals but I'm planning on building a simple circuit of the Meathead that I found a simple veroboard layout for.

Although i'm ordering the parts soon, I need to know what 470pF, 10nF, 47pF, 22nF to uF. Because the site I'm ordering from only has capsin uF.

i know it's probabaly really easy but any help will be appreciated!

Thanks!

hi...

1000pf = 1nf
1000nf = 1uF

Be careful at capacitor marking couse it varies from type and manufacturer.
For example, in ceramic you will find 102 this means that the value is in picofarads and you have 2 zeros at the right of the ten, so you will have 10 00 (1nF), if 101 its 100pf.
For polyester from sizes till 10nf its common to find values 2200 (wich means 2200pf = 2,2nF) or 0,033 (witch means 0,033uF = 33nF)
At first it may seem complicated but after some time you will get used to...

Cheers
