Circular pinouts are easy; usually they are N pins uniformly distributed at 
angles of 360/N, or N-1 pins distributed at 360/N degrees. Just use excel to 
calculate the coordinates.

For random pin arrangements, it's tricky and requires careful measurements with 
a digital caliper.

In the end that’s my idea – but I was hoping to find the datasheet with the 
correct measurements, instead of having to do them myself… Guess I’ll have to 
do it myself though ☺

I've made 'sockets' for IN-18, A-101, 5092, and b7971 with socket pins on a 
PCB. Afterwards, a 'collar' is 3D-printed to surround and protect the pins and 
make it look like a real socket.

[neonixie-l] Numitron IV-19 socket

[Manuel Azevedo]

Hello,

Does anybody know what is the socket for the IV-19 Numitron?
In Dieter's database it says that's the PL-31a, but that's the one for the 
IN-12 nixie. I have those sockets are they are very big for this tiny 
numitron.
The IN-2 sockets are also too small.

Even if I cannot find the socket, it's difficult to find information on 
this tiny tube, like the correct dimensions to make a PCB. Anybody got a 
datasheet?

Thanks,

Manuel

[neonixie-l] Re: tubes/valves and Global Shipping

[Dekatron42]

I know of these problem from personal experience, GSP cancelled shipping on 
items I bought and reimbursed me and the seller, sometimes part of the 
shipment has disappeared when passing through the GSP shipping sites as the 
items have been inspected and repacked (not only electronics but items like 
Barbie dolls, Lego and other stuff has turned up with parts missing).

But I can't find the limitations described above: “Consumer Electronics > 
Vintage Electronics > Vintage Audio & Video > Vintage Parts & Accessories > 
Vintage Tubes & Tube Sockets” and “Collectibles > Radio, Phonograph, TV, 
Phone > Radios > Parts & Tubes”

Can anyone show these with screen shots or describe how to show those 
limitations. I tried to find them but since I don't live in the US they 
don't apply to me as I can't use the GSP. I'd like to be able to show this 
to sellers that I am interested in buying items from who use GSP and I 
would like them to ship with a different courier, some gladly change the 
shipping but some say there are no limitations and don't want to change the 
shipping options.

/Martin
