What is a good selection of resistors?

post #1 of 5
Thread Starter 
I'm putting together a set of resistors (Vishay-Dale rn55) and I'd like suggestions as to what a good selection would be.

Based on the two most popular headwize amps, cmoy/hansen and szekeres, I'm currently planning on getting:
20, 220, 330, 1K, 2K, 2.2K, 4.7K, 10K, 100K, 220K

Are there any common resistances that I'm missing or would need for the majority of these kits?

Thanks,
~Andy

Trying to plan in advance what to have, it's a futile exercise... although current and voltage make math easy with the even 10s... 10/100/1k/10k/100k/1M/10M... and you can always parallel to get different values you're missing if you've got the board space...

If you don't plan on experimenting, then just get specifically what's needed for each project.

Also, what's the 20 for? If you're talking about the Szekeres, you need much MUCH higher wattage ones than those CMF/RNs. (they'd burn up in a split second)

Ok, so the 1/4 vs. 5 watts would smell bad. Scratch that one off

What I trying to do is get a set of resistors that would cover these two projects (1/4 watt only) and allows for a little experimentation. I have found some rn55s for .08 to .05 each in quantities of 100 or more at marshalls. I thought that I'd buy them in bulk, split them up into kits, then sell off the extra kits.

So a revised list should look like:
10, 100, 220, 330, 1K, 2K, 2.2K, 4.7K, 10K, 100K, 220K, 1M, 10M

What about something in between 10K and 100K?

Since rn55 is the size not the brand, what are they BTW? If they're something like Vishay-Dale CMFs or Riedons, that's a good price! If it's just generic metal films, that's an average price.

I'd add 2.2, 47, 470/680, 5.6k, 7.5k, 22k, 47k, 68k, etc... to fill it out... but not knowing what you want to DO is kinda hard to say. If you're planning on making resistor "packs" for selling to amp builders, there's no reason to get all nuts. Buying in 100s is alot of resistors, and if you never use ??? ohm ones, yea it's only $8 but still.

Yes, they are Vishay-Dales.

I mainly want to cover the two projects plus a couple extra for experimentation. Getting every possible resistance value gets to expensive to quick.

I guess I'll just add a 47K and be done with it.

Here is the link to the page I was looking at
