The Apex 375 was a varispeed amplifier into which one plugged the 300 or 350
motor. I used to own one. If ever there was a boat anchor...
Ampexes would change speed to a noticable amount as the weight of the tape
on one reel was shifted to the other.
I was iin a four way conversation at a friend's house many tears ago. A
Szell recording of an important work was playing at mid-low level in the
background. I head a pitch shift and mentioned it. We went back and
listened. Sure 'nuff. Apparently a take from one end of the reel was
editied into one from the other. We all heard it.
I don't know if it was true for all Ampex 300s and 350s or just ageing ones.
Recording a 1K tone on a tape and splicing the extremes should be a simple
