Additional Details


Imported from Germany by TSL (Technical Suppliers Limited) of Goldhawk Road, London W.12, the Harting
HM5 series of tape recorders were of extremely high quality.
Drive was via a very large Engel split-phase capacitor motor. The 5-inch diameter indirectly driven flywheel (weighing an impressive 4lbs) was statically balanced to within micro-grams. A very fast mechanical braking
system was employed and all shafts and bearings were precision ground to within micro-inches. As a result, wow and flutter figures were comparable to much more expensive tape recorders. Record/replay characteristics were to C.C.I.R. standards and Input mixing was possible.
