Hey..30 or 35 years ago, some of us worked in facilities where you tried not to
splice the tape because they weren't about to buy any more (and the splicing
tape was lousy anyway) so you got to be pretty good at doing a flying start! I
did many a 78 join that way and at least one of them was used on a CD reissue
last year because I couldn't find the original 78 to re-transfer it. Even today
I'll do the odd project on open reel, using alternating tracks, and I can still
cue the disc back a full turn, mark the spot on the reel where I want to cross
over, cue the reel back 4 turns and hit it the first time.
