There are 3 speed Tandbergs now being offered on ebay. Caveat Emptor!
My hot-rodded (multi head, multi format repro only) Ampex AG440 runs at any
speed between within and well past the range that you specify. Other
machines (also from other manufacturers)
that have DC servo capstans should rather easily do the same.
Depending upon the type of contents, also consider digitizing at double or
quadruple the recording speed. The files could then be repitched, including
'fooling' the system by sampling @ 88.2 KHz. I and other members of this
list can professionally perform these services.
