Thanks for the pictures - brings back memories :-)
I had misremembered the head mount orientation, but my memory of the had
size was fairly bit-free... I wish I could find the TM that had the head
tune instructions. I remember the "tune for squeal" bit, though and wish
I could find the quotation. Have been involved with a project involving
(a rather touchy) Vermont Research Drum of about 1 megaBIT capacity, I
found the adjustment procedure funny. The VRC drum used FeO and would
have been destroyed quickly by such an indelicate procedure.
