5.8 CD66, ZM1242, ZM1240, XN11 and XN12 Nixie Tubes.
Code configuration: A (see page 36)
Cell PCB Type:
CD66, ZM1240 and ZM1242:
These tubes have 1 lead at the
very back of the tube that needs to be removed. Ensure you only
clip the lead at the very back of the tube, this will leave you with
11 leads remaining and a gap at the back of the tube. Proceed as
for XN11 and XN12 below.
XN11 and XN12:
These tubes have 11 leads and a gap at the very
back of the tube.
To facilitate easy insertion of the flying leads into the small holes, it
helps enormously to trim the flying leads with a pair of scissors.
Start at one of the leads at the back of the tube. Then, working
around the tube, cut each sucessive lead approx 2mm shorter than
the previous one. This will allow you to feed each lead in in turn.
Now you can insert and solder in the tube. Insert the 11 leads into
the 11 holes with pads as shown below. Insert from the side of the
PCB with no markings.
