I just finished designing the IN-12A nixie clock's main board. I replaced the THD type 2n7000 FET with the SMD type 2n7002 FET to make the main board smaller. I also used the HV5622-PJ directly on the board without using a PLCC44 THD socket. (It is a little difficult for soldering - Could you tell me how to easily solder the PLCC and SOT-23 package? :D) There is no problem with DRC but I will check again if there is something wrong with the PCB and upload the file by tomorrow.

▲ Yippee! No DRC errors!

▲ All routed main board.
