Westinghouse didn't call that board a regulator card in a DMR control. I'm assuming by regulator card you guys mean the "acceleration device"? I had a problem once where the car would slowly move up in either direction. I found a blob of solder on the pileup separator on 32 relay. I can't remember which contact it was but when the car is not running (32=running relay)it shunts out the acceleration device. Also, the old style sockets were compression type and they upgraded to plugin sockets later- the compression type will cause lot's of problems.
