I didn't realize that you had lost the original tape. Have you considered re-interviewing him? Use the telephone. Weekend and evening rates are down to around five cents a minute. This stuff is well worth the $3.00/hour!When I do interviews on the phone, I use a little suction cup device (again Radio Shack and again just a couple of dollars. It connects into the microphone jack of a tape recorder and picks up both incoming and outgoing conversation. You just stick it on the back of the phone. Having a scratchy voice is better than no voice. You can do it to ask follow up questions from your reading of the typescript.
