Advice for Parts Bin? - Resistors

[timd]

I'm going to buy an organizer for resistors (and more resistors themselves) for stompbox making. I'm going to put in a big order soon, and since there are a ton of resistor values out there, I want to know if there is a short list of common ones that appear often when making pedals. Thanks in advance!

Look for the E12 series:

1.0, 1.2, 1.5, 1.8, 2.2, 2.7, 3.3, 3.9, 4.7, 5.6, 6.8, 8.2 and 10.0
* 10^{-1 to 6}

Hi Timd,

More experienced builders will prob have better advise, but for me, i have about 7 draws for resistors, and i put them in ranges, like 1 ohm - 99 ohms, 100 - 999, 1k to 99k, etc etc.

I have a decent amount of 100 ohm res's, but i have bulk of 1k, 10k, 100k, and 1m.  Also, 10uf & 100uf electros, and 10nf & 100nf box.  They come up alot. A few 100pf ceramics.  2n5088 and j201's for transistors.

I hope thats a start for you!

Someone mentioned before that these were quite common
100ohm, 220ohm, 470ohm, 1k, 2k2, 4k7, 6k8, 10k, 22k, 33k, 47k, 68k, 100k, 220k, 470k, 680k, 1meg

Bravo.

So it wasnt just my imagination, i was using those values alot I'm bookmarking that page, thanks for sharing!

Ignore what the pic is of, look in the background at the coin envelopes.  That's the entire E12 series from 0 ohms to 10M ohms, 83 values if I remember right, all in a ~11" x 3" space.  Next to it are three other rows of caps.  The coin envelopes are held in photo boxes which fit two rows of the #5-1/2 coin envelopes I'm using (#6 is more common and will work too, I am using 5-1/2 for their height so I can keep these in the desk drawer on my bench). The photo boxes allow me to grab a box and go if needed.

I have drawers for
1)less than 100R
2)100R
3)between 100R and 1K
4)1K
5)between 1K and 10K
6)10K
7)between 10K and 1M
8)1M
9)more than 1M

Ignore what the pic is of,

... As if I could ignore that if I tried.

What the hell is that awesome looking thing?

[deadastronaut]

^ mad looking thing...


i stick all my 1--- values in one drawer
2--- in another...etc...

same with caps...labelled by nf/pf...not  00000000000000000000000000000000000000000000000000000000000000.1

AC to DC power supply with regulation?

AC to DC power supply with regulation?

Correct... at 400v.  B+ in is up around 500v unloaded, the MOSFET drops the voltage down to a regulated ~410v.  This is how I "breadboard" tube turret layouts.  It proves out both the circuit and the layout (to a large extent, the component leads being long could cause some issues depending on the circuit).  I've done entire amps this way, works well and is inexpensive.

> 100ohm, 220ohm, 470ohm, 1k, 2k2, 4k7, 6k8, 10k, 22k, 33k, 47k, 68k, 100k, 220k, 470k, 680k, 1meg

Agree; actually I did a lot of work without the "68" values.

I used the second plan modified. Drawer per decade. Resistors used to have color stripes big enough and bold enough I could read them. So all the "brown" (100-999) one drawer, all the "red" (1K-9k9) in the next, etc. One drawer for under-100, one for 10Meg and over.

<100
brown
red
orange
yellow
green
>10Meg

8 drawers, two rows of a 4-wide parts cabinet.

IME: skewed to the 1Meg and 470K often used for guitar interfacing; general (non-guitar) won't use so many of these two values.

Do you guys put the 1/2W and 1/4W, carbon film and metal films in the same location/drawer, or different places ?

[defaced]

Yes, I sort by type.  What you see in my picture are my 1/4w metal film.  On the floor are my VIshay CCF60 that I use for my amps.  Stuffed away in a box somewhere are the carbon film assortment packs I got from Radio Shack.  And last but not least, the thick film 1206 SMT resistors I have are in little box thingys on the shelf (terrible storage solution for those). 

[frank_p]

Thanks for your advice Super Evil ! 

[DavenPaget]

I sort by the E12 series ,
10,12,15,18,22,27,33,39,47,68,82

I have found some cigar boxes that are the right size.
