DAMNED caps

Hello, do you think that WIMA 20% tolerance are good for building a TS808 or should i chose smaller tolerance caps

?
Do they affect sound quality?

It's not easy (nor cheap) to find caps better than 20% tolerance. Go ahead.

OK, I'll try!

WIMA is very nice quality. the tolerance shouldn't make a noticeable difference (at least, one not lost to tone controls and significant THD

)

what do you think about 10% tolerance green capacitors?

Tight.

I'd use 'em all the time, if I got 'em, but I'm not that picky...or rich.
Tight...er than 20%, which I think will hit all targets close enough for TS work...I generally tweek anyway, opt for derivative, or something else.
For precision targetting, like say what...theremin, or something where even a small drift can throw things off, opting for tighter tolerances might be critical.
For the TS, hitting target cap values is kind of like hitting the side of a barn that can be moved with the Tone Control. You'll hit it every time using 20% caps...of course if the aim is way off to the right for some reason as 'you like to aim left' simply adjust the value of the cap [by say 50% -100%] that's not letting you hit to the far left.

Ok many thanks for your answers

, let me explain better. TS schematic I've found needs 3 film caps.
I have WIMA 20% tolerance and Green caps versions of all three caps. Two of the last ones are 10 % and the other green cap (the one wich is 0,01uF) is 5 % tolerance. This cap has been desoldered from some PC speakers. As a newbie, I ask if the cap could have been damged. I am so repetitive because I don't know if the efficiency of desoldered components is closer enough to the brand new ones. What do you think about this?

It's unlikely for a desoldered cap to change value. It might be totally destroyed if you heated it too long, but I can't see it actually changing to another value.
What I'd do: build the unit using the cap & if the box sounds good, leave it there.

Next thing you'll see is people selling "sorted" capacitors, with a tolerance of +/- 0.1%, and which claim to make FX sound way better

or 'chewy' or 'crunchy' or 'creamy' or 'buttery smooth' or 'lush' or 'vintage' or 'fat' or 'boutique' or 'rounded' or 'biting'.
Dont mind me

I hope so, I want to sound just like Jimi. I think my caps are messing me all up.

P.S. That was a joke $:-\$
