Hi
Hope some one smarter than me can help me a bit
I have this old Double or even machine.
The top print where the lights is does not work, but the game works fine - its just the lights.
I have checked and repaired the PSU, so now all the correct volts are present, but the lights still not work.
All the bulbs are fine - just one is lighting up.
So i guess that the missing lights i caused by the controller board.
I have replaced all the caps on the board but no difference (the old one where blown)
So my attention is on the IC's on the board now
There is a lot but mostly
CD4011AE ->

https://www.datasheets360.com/pdf/4567507543728082358I am unable to find the IC's online - so i have got some
CD4011UBE ->

Again I need som expert advice
My plan is to put in some sockets at the PCB when i remove the old IC's so it is easier to change the IC's in the future.
