Before the pictures in this thread start, there was actually a ton of work that wont be shown, as i will do another thread just dedicated to that stage shortly, but in short i started with a pretty horrific old pcb of Nixdorf's.
I desoldered the entire board, opened every switch, cleaned the contacts and housings, swapped the springs and then gave the switch tops and ultrasonic bath, finally putting them all back together and hand picking the best ones for this board, which leads me to where we began......
A pretty crusty and incredibly dusty KMAC HAPPY
Stripped it down
De soldered all the blues, which were largely knackered
Ended up cleaning out the plate with a little lemon oil to break down some of the buildup on it and then thoroughly cleaned that off and shined it up and then tuned the stabs
Re soldered her up with the tuned Nixies
This is the finished result
All tested, gonna give it one final clean up shortly and take some proper pics of it
