Many thanks for taking the lead and all the puzzle work.
I needed some time to find the "instructions" - the thread gets long - but I finally found them.
I assume other may have same issue, so made a copy here also.

Quote
This will be a cooperative effort. Everybody who wants to receive some of these please follow these simple
instructions.

instructions

1. Everybody who is not in the USA, please add your country beside your name on the list. Just copy the list, paste the list into a new post on this thread, and add your country beside your name.

2. If you are not on the list, and you want to be on the list, copy the list, add your name and country to the bottom of the list and post the amended list.

Housekeeping items

1. You will need to pay for United States Postal Service (USPS) shipping of the parts to your location. I can accept Paypal. If you cannot send payment for the shipping then you will have to find another way to purchase these for yourself. I have shipped stuff to just about every country in the world, so , chances are that USPS can get these parts to you no matter where you are. After I have a representative package to ship, I can post the price of shipping to various countries.

2. If we end up with 150 people on this list then everybody gets 2.8667 pieces. That is just the arithmetic of the situation. Lets see how this list develops and we can discuss it. My personal opinion is that 10 pcs is the minimum that would be interesting. That means we can accept up to 43 people on this list.

3. When it is time to ship, I will send you a PM on this site with an invoice and instructions for sending payment for shipping.

4. I have a day job. It takes me out of town on travel sometimes. There will be some days that I will not be able to post on this thread and will not have access to PMs etc.

I can't see the schematics though, perhaps you can attach it? I'll need PDF or so to redraw it in my CAD.
Perhaps include me into list too then, 10pcs Taipei, Asia :) I'd make a board , perhaps with room for 10K resistor, and call it 3458A-NutKit :D

I'm interested as well in this board. Are you going to make separate thread about it?
Resistors array I prefer Vishay NOMCA and pots Bourns 3250W or VPG 1280G.
Resistors nothing fancy, Vishay UXB series or PTF56.

What do you plan to use as 10k resistor? Vishay foil Z203?
Can we reuse some trimming technique to exact 10k?
Or to reduce BOM using cheap Vishay NOMCA in series/parallel configuration with pot.

Resistors array I prefer Vishay NOMCA and pots Bourns 3250W or VPG 1280G.

plesa, the NOMCA series looks good for the 5+3 array of 20k, but I only can find them in multiples of 500.
The Bourns pots are PWW and very good but, 22€ each, the Vishay pots are 16€ each.

Resistors nothing fancy, Vishay UXB series or PTF56.

Here any resistors like UPW-20/50 series, Edwin, UXB, PTF,  etc, should be ok.

What do you plan to use as 10k resistor? Vishay foil Z203?
Can we reuse some trimming technique to exact 10k?
Or to reduce BOM using cheap Vishay NOMCA in series/parallel configuration with pot.

How about using 4x40k in parallel, this way cheap PWW, UXB etc could be use, sinc all the tempco is split between them, we could use 4 wire here.

Thanks VintageNut!
PS what state are you sending these from?
Zlymex was kind enough to purchase and send 430 pcs of a 2DW233 with what looks like a 4-14 date code from his picture on the 2DW original thread.
3. When it is time to ship, I will send you a PM on this site with an invoice and instructions for sending payment for shipping.

There are NOMCA 20k for 5.18 GBP on Farnell in single quantities..

Depends on the farnell website, in the .es only 10 pieces, on the .pt the 20k doesn't exist.

The first hit was Digikey and they show only 500 min. order.

I see a lot of annotations asking for way more than 430/people...    Like does pelule want 0 if he can't get 20?  My original request was for 20, but I'm putting 10+ to indicate whatever a "share" ends up being once it's divvied up. 

Really appreciate zlymex and VintageNut for the time and expense making this possible!

@metrologist
Did you read the instruction? (scroll up in this thread)?
@ Flinstone
would be fair, to have placed your name at the end of that list instead of the top. But doesn't matter anyhow.
You will learn something new every single day

Where we are right now with the list, there are 35 people with a few yet to respond with confirmation.

430 pcs divided by 35 people, truncated to a whole number is 12 pcs per person.

We can accommodate a few more people. I will cut off additions at 43 people so that everybody gets at least 10 pcs. i will announce when the list is frozen. If someone is not interested because the quantity is too low, you can delete yourself from the list.

I have started a spreadsheet so that i can keep organized. Thanks to everyone for managing your own place on the list. Everybody will be treated equal no matter when they joined. We will all get enough parts to make some PCBs and have some new voltage references.

best regards,

VintageNut
