log law pots ratio?
 

I always thought log law was mid track resistance 10 percent of whole track.
Just come across a stereo slider in a Yamaha mixer amp labelled A10K x2 ,
fair enough meaning log, but mid track is 25 percent of 10K . Natural log
rather than to base 10 ? 2527

** A virtually impossibility....


log law was mid track resistance 10 percent of whole track.

** Yup.

** Nope.


but mid track is 25 percent of 10K . Natural log

** A = Audio Taper.

C or D = log.

E = reverse log.

Audio taper is a marketing compromise curve that sells amplifiers.

No. That's D-Taper, the pot I was after.

Would that be 10A, 15A or 25A?

Nothing says it is an Alps pot at all.

And nothing says Nutcase Kook measured it correctly.

You ****ing stupid, lying ****.

The factory could have installed the wrong elements.

Assuming Cook is measuring the midpoint resistance as part of some
troubleshooting process on a customer's defective equipment, I'd like
to know (1) was this channel always bad? and (2) what reading he gets
from the other channels. This would show if it's an isolated
manufacturing mistake, or if the pot was damaged during operation. If
the midpoint resistance was the 1K that the A-taper suggests, then if
some fault drove it to 2.5K, I would expect the overall resistance to
be 1.5K (or better) more. I'd like to know (3) what the overall
resistance now is (4) for both sides of the pot, (5) for similar parts
from the other channels, because I can't picture the same fault
condition affecting multiple channels identically at the same time.

Back up together enough for testing now. Only one one pot removed.
Actual reading was 11.2K and 8.7K/2.5K midpoint and to about +/-0.1K same
readings the other track . Whether that out of speciness from 10K indicates
overheating or something I've no idea but is is same both sides

** Shame how YOU have the wrong brain installed.

Donkey brains instead of human.

25% at mid point is within tolerance for an " A " taper pot.

Sample size = 1?

I suppose, though, in Allison World the pot could be linear -- 25%
ratio is closer to 50% (nominal linear value at midpoint) than it is
to 10% (nominal audio taper at midpoint)

Here's a report from a hobbyist who found that the 50% point of common
"audio taper" potentiometers ranged from 6% of total resistance to
15%. So the source of Phil's data -- 25% -- still seems to be his ass.
