Apparently these chips were used in industrial printer machines. Searching on ebay for "kodak charge driver board" does yield some results of used PCBs with HV3418 onboard. Those boards are expensive but so far seem to be the only way to get the chips. I got myself one of those boards, hopefully the chips work.
If anyone find a different source, please add it here! Those chips are super useful for variety of neon projects.
