Replacing Velo DD12 amp

Hi, I have a Velodyne DD12 that produces distorted sound due to damaged electronics. The driver and the box are still in good condition. Has anybody ever tried to replace the plate amplifier of this sub with some generic DIY plate amp? Any suggestion on which plate amp will fit the form factor of the original module? I know that doing so, I will lose the servo feedback feature as well as some other control features of the sub, but I am fine with that. Will I be getting a good bass response by using a replacement plate amp assuming there is one that fits? Will appreciate any suggestion that you guys might have in utilizing the still-good driver and cabinet of the sub.
