I'm currently on the search for parts to convert my Otari MX70-16 to 16 track. I intend to keep the 8T headstack. If anyone has a 16T headstack and 8 channel cards in good condition then please let me know :-). Either/or as I'm not in a mad rush for it. I don't need a head report (just close-up photos), as long as the asking price isn't ridiculous. Thanks in advance!
