trying to figure out a type and source for these components.

trying my first few builds. saw this klon clone and trying to source similar parts to compare to the other one I just built. I know it's probably going to be indistinguishable but I like the way it looks. my first one I built using the BoM from the tone geek's mouser link and it sounds amazing. im not expecting much different from this one.

1. I need to find WIMA capacitors in the following values. im not sure they offer all these values. mouser doesnt seem to list them. is there something equjivalently overpriced and snake oil I can use to replace them

2n2
3n9
27nf
68nf
82nf

2. what are the 4 large red 1uf capacitors and the two 47uf silver capacitors likely on the side of the board. I believe these are all in the power supply so I may just get the highest end nichicon caps that fit there

3. I have already sourced the tight tolerance black H8 resistors. just stinks 2 values are backordered from mouser.

4. I also have plenty of the nichicon muse bi-polar capacitors. those were not fun to find. especially the 4.7uf ones.

here is the parts reference for the build out.
 
I'm sure a lot of the really experienced people in here would tell you that there is really not a lot of magic in fancy parts..... Some things are worth bumping up the quality here and there, but honestly most of the crap you read on the interwebs is hype. It's actually how do you personally perceive what you built or someone else built unbiased... If it sounds good.. it is good...
 
I knew thats what most people would say. to be honest, im not expecting to to sound any better. its not like I used junk parts for my other build. if anything sounds better id honestly just assume it was from using tighter tolerance values. or a better set of diodes. its more of an exercise of why not than a "this is going to be the best ever". there are so few parts in a klon the cost difference is negligible either way
 
by all mean..... build one with all the wima and nichicon gold goodies and dale/vishay resistors... but build the same thing with all parts from tayda or even amazon... I' think you'll surprise yourself.... I'ts ok to get middle of the road stuff.. I really don't think its worth buying all premium parts .. even for my personal builds.....

WIMA. It can be read on the cap between the two silver caps. Not sure of anything else you asked.

Whether the various brands/types/vintage different components make a difference or not has been debated for a long time and as you see the debate continues... Personally I only build one-offs for myself so purchasing top shelf parts isn't as big of an impact as purchasing parts for say 25+ copies of the same pedal.

Digikey is another place to check for components.

Thanks. I think this pedal build will cost less than $40 difference more than my other build. That’s like 7 large eggs at current prices

also, wima doesnt seem to make anything in these value. I was hoping to find something other than the white Kemet that look kinda ugly. but thats probably what ill do the rest in.

mouser sometimes has odd search parameters--they don't really like listing under the nanofarad range.

2.2 nf usually shows up as 2200pf, for example. 10 nf will be 0.01 uf. try searching under those terms.

Here's the wima 2.2 nf found as "wima 2200 pf," there are several choices for you. [edit: there's one with 2.5% tolerance! That's pretty tight. I usually shoot for 5-10%]

thanks. I did finally figure out how they are listed. they dont seem to stock 27nf but they have 22nf. I could order a few in 20% tolerance and see what gets me close in the correct pin spacing for the board. there doesn't seem to be anything close to the 82nf one though. ive kinda given up on marking it look uniform at this point and will most likely just order the 4 caps I need from kemet
 
You'll probably find everything you need at 10% or less tolerance, more precise is better. That's my biggest deciding criteria. I don't care as much about brand name, although all things being equal, I'll choose WIMA just because I like the color--if it's not too much more expensive.

I meant buying a 22nf 20% capacitor trying to find one that tests closer to the 27nf the circuit calls for. normally ill put the tightest tolerance ones available if its in the correct value. if I go with 22nf @ 5% the highest value I could potentially see is 23nf. but if I went 20% I could potentially see 26.4nf which is within 5% of the value I need. its a guessing game of how close you get to the limits of the values though. ive never tested.

im mostly looking for wimp to just get them all red. id potentially get something else if I needed to.
 
Gotcha on the tolerances. In my experiences, it's rare you get anything on the far end of the tolerances and WIMA is a pretty consistent manufacturer, but you might luck out--or have bad luck that is good luck.

There's always red spray paint or nail polish hahaha... you could start your own brand of WIMA knockoffs--if you do, please print the capacitor values on the top as well as the sides. Hard to read into capacitor sandwiches for no good reason, WIMA. You can also list the GD values in nf instead of always uf like everybody else too.
 
Won’t it look soo much better if I could put 4 more red boxes in there instead of ugly white ones.

Data sheets are very useful. Wima publishes them for each series and lists the specifications for the devices within it. Relevant to your search, the MKS2 series, for example, does not include 27nF parts.

Yes. Unfortunately 3 of the 4 values I need to source they don’t make. So I’ll have to fill it with a different color
