I was just given a reel of Ampex 456 at +3/250 15 ips recorded in 1982 to replace a vocal track and mix. My MCI is setup for +6/250 30ips. (1) How do/will I know if the tape will require baking. (2) How will I need to set up the MCI. If I switch to IEC will this be sufficent for record (1 or 2 tracks) and playback? I realize that to most of you these are probably lame questions but this is my first expetience with this so please give me some options.
