Any enthusiasts or techs know how to properly calibrate an Otari MX5050? I have one that I don't know what tape it's biased for, want to get it set for RTM sm911. I've seen a tutorial but it's above my skill level. May need some caps due to "wind hitting microphone" noise I get when recording but I hear different stories about that.
