On one of the Technics machines (which playback in 1/2 and 1/4 track stereo) it depends on which model (1500 or 1506) on which head playback is first and which is last. A 1500 records in 1/2 track stereo and plays back in 1/2 and 1/4 track stereo. Once again the old rule applies. Erase>Record>Playback. If it records in 1/2 track stereo than the 4th head "must" be the 1/2 track playback head. If it's a 1506 which records in 1/4 track stereo, than the 4th head "must" be a 1/4 track playback head.
