I have both of these machines in various states of disrepair. The 1216 doesn't seem to want to run at all, the 1226 won't shut off. The 1226 seems to have a somewhat better arm, the 1216 has 78 playback capability. The question is...am I going to have any luck transplanting the 1226's motor and arm assembly to the 1216? The 1226 might also have a somewhat heavier platter. If so, that would also be moved to the 1216 chassis.
