what's the most common resistor you guys use?

That being said - some tolerances SHULD be taken as the absolute maximum dont-pass-it-or-we-will-send-killer-goats-after you.

my understanding is like overclocking a CPU,

I prefer Vishay-Dale RN55 or RN60 1% series (depending on the pcb's lead spacing and power requirements). They are superb quality but are not obcenely priced like most "boutique" resistors. Despite the sausage appearance I really like the fact that they are marked with actual numerals. Maybe my eyes are going bad, but I have a hard time with color bands nowadays.

That said, I doubt that you will hear or measure an actual difference between any good quality metal film resistors in a headphone amp application. Panasonic, Yageo, Koa-Speer, Xicon, ... they are all good.

For active filter or phono stage RIAA EQ use, sometimes I go with 0.1% resistors for accuracy.

in other words: for real-life usage scenarios, a 1/8W rn55 would be equivalent to a 1/4W generic, and a 1/4W rn55 would be equivalent to a 1/2W generic.

I'm with AMB in the fact that I really appreciate the easy to recognize numeric marking system on VD resistors. It makes trouble shooting so much easier, provided that you take the time to have the value face up, which I do.

My 2¢,

Nate

PRP, Holco, Kiwame, and a few others (Mills, Reidon, Ohmite) also do this. I agree it is a nice feature.

RN55 is 1/8W. 1/4W will be RN60, which is a fatter sausage...

I use Vishay RN55 and RN60 almost exclusively.

my 2.0ghz amd chip shows up in the windows "observation" utility as running at 2.4ghz...

military standards require that the resistors be rated at that rating. "non-military" consumer standards, the resistors are capiable of tollerating much more power disipation.

no no - you must have misunderstood me.

what i meant was that the RN series are milspec resistors, hence the milspec rating of '1/8W' for the RN55 would corresspond to 1/4W for a 'civilian' resistor.

really? I didn't know that! no wonder in all those "post your build" pics, they are full of little sausages! I should know this earlier then I don't have to stuck on Yageo generic ones.

Just for independent confirmation puposes you should read this. Also, this confirms my belief that the military really does practice the "Why buy one when you can have two at twice the price?" theory.

YES! Who ever decided that color bands were a good way to code resistors wasn't color "blind". I've NEVER been able to read resistor values by color bands (this a sex chromosome linked trait, and thus common in men). Although it's a bit tedious, you can easily sort out Vishay-Dale resistors if they end up in a pile on the bench, and I always mount them with the values facing up. It makes trouble shooting at the end of the build sooooo much easier.......

 

[n_maher]

Just so folks who aren't familiar with Vishay Dale resistors get an idea of what we're talking about here's a shot of my PPA. Pretty dang easy to figure out what is what, eh? For example the 1001F resistor located to the vacant R7R position is a 1000 ohm resistor. 100 + 1 zero. The 4703F located down and to the left from that, 470,000ohm or 470kohm. You get the picture, literally

something nice about color-coded resistors is it dosnt mater if your in a rush and solder em in "upside-down" but you should not rush anyways...

edit: happy post numbero 1000 to me.
