Socket Receptacles for Nixie Tube
The next step is to place the 14 or 11 sockets for the Nixie Tube.
For the IN-18 tube there are 14 sockets to place and for the IN-8
tube there are 11 sockets to place. It is easiest to work from the
component side, and after inserting each socket, solder from above
on the component side. This helps you keep it pointing vertically as
you solder it. Once all 14 or 11 sockets have been soldered in, go
around and ensure they are all vertical and equally spaced.
It is a good idea at this point to offer the tube up to test if all the
sockets mate up with the tube pins. Make small adjustments to
sockets as needed, before finally pushing the tube into place to
make a test fit. Remove the tube and put away safely again.
Figure 17 (IN-18) and figure 18 (IN-8) show the PCB with the
socket receptacles placed.
