Are you holding the resistors in your fingers when you measure them? That can make for some big errors depending on your skin moisture level. Is the battery in your DMM fresh?
Dumb question: Are the markings on the resistors the same? (Wondering if
you might have been received a wrong value resistor.) Otherwise it would be pretty
unusual for a resistor to be this much out of spec.

Well clearly the 331R is "perfect" as the rated tolerance is for the resistors is 1%. 1% resistors are considered "overkill" by many.
I doubt very much that Nelson is assuming 1% resistors. More like 10% probably
It surprises me that you measured 282R for the second one but I doubt it makes any difference at all.
The 282R is surprising as the Vishay-Dale resistors usually exceed spec.
I'm hoping Zennie or Nelsonie pops up and puts your mind at ease. If not- we'll talk....

I see a 332R for R4. I think that's part of the feedback loop. If that is the case,
I would certainly want the same for both channels.

Well do we all agree that 331 is "awesome"?
I can have another couple resistors sent out but they are unlikely to be as close as the 331R.
I think we all agree that 282R is a surprising, and if we send yoiu some more they'll be a lot closer.

Hi fellas,
Who do I contact if I ordered the Sony/Pass VFET kit (whole kit) & the supplemental kit? I was in batch 2 and I ordered on 10/23/16. Order# DAS-2249.
Thanks,
Anand.

if we are talking about R4 position ( as Denis sez - part of NFB net) , it is absolutely critical that they're in 1% between channels
so , to ichiban - say tnx , and buy two 330R metalfilms locally .......
My thoughts also, thanks.
For a DALE it just seemed unusual.😱
Tomorrow I will check the variance on the others again.😀
Thanks. (I was wondering if they might have been loose RN55 resistors
with goofy resistance codes that were mispackaged.)
I think your diligence shows why it's always a good idea to measure the parts
before use. (But dang it's weird for a CMF55 to be out of spec like that.)
Hopefully other members will also measure their parts, in case there are
other outliers...
Cheers,
Dennis
Yes always measure all resistors to know real component specyfications and i can match R pairs for symmetry
so my left and right pcb circuits are "mirror images" ..but wait...we have trimmers so is not necessairy.
I do anyway is hobby pleasure on the work bench.
Dale and Vishay or TCC i tested last month's was all in spec ok.
I like clean resistors legs oxidation to make them brights & shine
that soldering flow is little easer and good for sound quality as well.
Do you see clean legs R on my photo ?
Greetings 🙂

Ichiban, sorry everyone was scheptical but you clearly have experience and did things correctly. As we all said, it's SO unusual to have the Vishay-Dales be worse than spec, that no one could believe it!
I can mail you a couple if we still have some extras, we probably do..if you can't get them locally. You can get hold of me via PM

😀 Googling and if compare temperature with soldering station this is much "hotter " pairs 😉
Best regards
Haha ...yours is not the same resistors ...little more oxided legs 😀
