I am imagining the mechanism, and it sounds like an interesting idea. You could probably even mod it into a stock pot. I'll have to try that...

Bob Pease used to have a thing about them. On his first job at Philbrick the eyelets would cause failures by thermal movement tearing the copper foil.
I suspect that since they are still around they may have fixed that issue.
If I was a circuit, I'd behave!

What do you mean by mod it into a stock pot?
EDIT: Oh, do you mean mod a stock pot to eliminate the wiper contact?

...Pease's book on analog troubleshooting should be required reading for anyone putting their hands into a piece of electronics.
😱

The rest of the electronics world struggles with normal PCBs and normal PTH holes, no need for outdated techniques really, but this is audio an I believe sometimes that certain areas of audio exists in the twilight zone😛
Wonderful world, to learn from an Australian that this fine Dutch product exists.😎
As I usually do, I pick up specific test equipment to learn and see what affects this/that have then get rid of it. For jitter, I have on order the Yokogawa TA320. It will measure jitter and give a distribution plot.... down to +/- 100pSec full scale. I will see what i have and how to improve it.... also what makes it worse and how much worse. Enough about what perfect communications theory and other such ideal conditions and the like says. I'm sure to learn a lot about all sorts of things with it re jitter.

oh, I don't know. Just ask Philips about the first couple generations of CD players that had solder connection problems with their "griblets". Their terminology, not mine.

I'd love to see what you will find out with it. I had TA320 for some time but wasn't completely satisfied with it - not enough resolution for my needs. I later upgraded to TA520 (still have it), but it also doesn't have enough resolution to measure jitter in tens of pSec range.
True. You cannot change the statement to "Wonderful world, to learn from an Australian that this fine Korean product exists" because it would have different meaning 😀
The problem with eyelets is the PCB- difference of the coefficient of thermal expansion and creep between PCB and metal are not conducive to long term reliability.
The model offered by Acoustic Dimension up till a couple of years ago was powder coated in blue.
Oldy page from the site, on the top : Volume control main page, 41 step attenuator, Amtrans, Audio Note, TKD 2CP-2511
Identical to the ones manufactured by Allnic in Korea, if you're lucky the name of the manufacturer is even in copper on the boards inside.(I have a couple of the prettier ones)
