Hey guys. Got a box of various parts from a friend, and I have no problem getting the values of everything, except one type of capacitor.

They are green capacitors. No clue on manufacturer or anything. All I know is the code on one side. The code is written sideways from the radial leads. One code is:

2A502K

My guess for this would be a .005 uF with a 10% tolerance, but I have no clue what the 2A would be for.

Most of them have this code, but there are a few others. If someone can tell...

Anyone know what is meant by the CR1 & CR2 reference designators in this schematic ? CR used to be used for diodes but I don't think that's what's called for here.

Nice forum!

can someone please explain how parallel caps to ground affect gain and biasing in BJT or FET gain stages? i have heard a lot of things, like will increase distortion , will affect bass , etc. but have never found a concise explanation of what is going on here. anyone want to field this one?

Hello Folks,

I'm new in this board and i have built few pedals in a past. I consider myself as an
newbie in this do-it-yourself stompbox scene. However, i'm still learning things
and i want know what you guys think about component quality. So, is there any manufacturers,
models, materials i should avoid when building my own high quality pedal .

Hi everyone,

i'm a bit confused with the type of capacitors i should use when i'm building a stompbox using a existing shem because the schem don't say what type of capacitors are used

for instance, ok..i know when they use a polarized or non-polarized capacitor, but is a polarized electrolytic or tantalum one? the same for non-polarized...is ceramic or polyester ??

there are no difference between electrolytic or tantalum and ceramic or polyester ?

thanks

When I look at a schematic and see various unpolarized capacitor circuit symbols, how do I decide what type (i.e., polyester film, electrolytic, maybe others I haven't learned about yet) I should use in a build?
