These don't come up too often. Here is a 1/2" preview headblock that has been modified to be used with a VMS80 with a 0.5 revolution delay time. It could be put back to 0.6 revolution if necessary. I put the headblock on my A80 1/2" preview deck and both heads worked and calibrated up. Just the headblock, no complete 1/2" conversion kit available. 2K USD.
