I would like to find out the distance from the REC-head air gap of a BTR 2 to the air gap of its REPRO-head. Do you remember that? Or have any notes about it, or a clue where I can obtain these information?
I'd like to know the same at a Studer J37. The reason is the inclusion of these two machines into setting up ADT, as you might remember.
Besides I'm researching about devices for time stretch / compression without pitch shifting magnetic tape recordings and vice versa - admittedly already another question.
Did you ever use any machines for separating pitch from speed alteration, ie. something like the "Eltro Mk. II" or something? What about the quality of a signal processed in such a way?
Thanks a lot for your attention. thumbsup
P.S. I'm collecting these information for a scientific coursework, written within my audio engineer diploma education at SAE Institute Berlin...
