Title: Replacments parts CD4011AE CD4012AE -> CD4011UBE  possible?

Hi  :cheers:

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/4567507543728082358 (https://www.datasheets360.com/pdf/4567507543728082358)
CD4012AE -> https://www.datasheets360.com/pdf/4567507543728082358 (https://www.datasheets360.com/pdf/4567507543728082358)

I am unable to find the IC's online - so i have got some
CD4011UBE -> http://www.ti.com/general/docs/suppproductinfo.tsp?distId=26&gotoUrl=http%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fcd4011ub (http://www.ti.com/general/docs/suppproductinfo.tsp?distId=26&gotoUrl=http%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fcd4011ub)

If I compare the two IC's data sheet they look the same.. can i replace the old ones with the new?  ???
Again I need som expert advice  :applaud:

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.  :)

A bit more information and pictures of the OLD stuff :)

The only lights that light up is the one "even" in right side.
The lights in the middle all lights up, that is background lights so i guess only the lights in the side has to do something when i pull the handle

A update more :)

I have checked that there is going power to the CD4011AE CD4012AE at pin 1 (+) and pin 14 (-)
All the chips has around 13V in.

Its also random what bulb that light up when i turn the machine on..
Now it is the top one who is lighting up...?!?
