The 5001 and 5005 models were 'mono' machines
The tape drum is not readily accessible unless you undo
the back cover
A fully recorded tape drum could not be removed and
changed for another 'blank' one (except by a repair engineer), so it was not as
flexible as standard reel-to-reel tape recorders and the soon-to-follow audio cassette
Additional tape drums were never sold to consumers, so
once the tape was full, you could only play what you'd recorded, or over-record earlier
recordings with new recordings – not an optimal solution
Recordings are limited to 22 minutes, or exceptionally 30
mins using Jim Weir's dual-spindled pulley
(See also a brief discussion about the 22-minute recording
feature in Autoreverse suggested by
Unless you were lucky enough to have bought the specially
made 'Logbook' (Programmheft)1 at the time, you
had to make your own log of all the music and radio programmes you'd recorded, and
on which track. Without such a logging system for locating your recordings on the
tape, you were up a gum tree!
The tape unit will only record one track at a time.
1. Schaub-Lorenz's alphabetically arranged 'Logbook' is printed with
all the letters from 'A' to 'O', and includes the letter 'I' (i.e. track sector 'I') which,
as is pointed out in 126
track 'jukebox', was never printed on the music center's alphanumeric
track-selection dial! An oversight on the part of Schaub-Lorenz's marketing and production
teams, no doubt.
