Additional Details

Description

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.
