Problems with tuner unit
Once I'd got
the music center I'd bought on eBay back to the Netherlands, I turned it on to see whether it
worked properly. The FM radio still worked fine as did the AFC, but the AM tuning (for LW/MW/SW)
appeared to be jammed. Perhaps the tuning cord had somehow got tangled up around one of the
pulleys, I thought.
Tape unit fails continuous-play
unit worked pretty well. At the end of a track, the tape unit would automatically click to the
next track and then rewind. However, once rewound, it failed to move on to the next track as it

that the machine was 40 years old!
'record' function didn't work, which also meant that no new recordings could be made and that
unwanted recordings could not be erased from the tape. I was advised to discontinue running the
tape unit until it could be looked at, as the tape had a tendency to shred. (See

Rule of thumb for gauging hi-fi
A rule of thumb for gauging the quality of audio and hi-fi equipment
is the number of transistors, diodes and relays it has. The Schaub-Lorenz Music Center 5001
26 transistors (27 in the 5005 model)
1 Zener diode
8 different types of relays

In addition, it has 11 push buttons, a 4-band radio including FM with
an automatic frequency control (AFC), a 126-track reel-to-reel tape recorder with an alphanumeric
track-selection dial, two loudspeakers, and a top-quality amplifier.

the unique features of this Schaub-Lorenz Music Center 5001 is its tape unit. It has been
described as a 'reel-to-reel jukebox'. The tape unit has a dial that can be turned clockwise or
anticlockwise from dial sector A to dial sector O. (Sector 'I' was never used). The tape unit
has a 10-cm (4 inch) wide magnetic tape that allows you to record either directly from the radio
or from a record player.
126 recordable tracks: 46.2 hours
the dial's 14 letters (tape 'sectors') is divided into 9 further recording tracks, giving a
grand total of 126 tracks (14 x 9), each of 22 minutes in length. This offers a total of 46.2
hours of recording, unequalled by any other consumer tape recorder of its generation. In fact,
if you'd wanted, you could have recorded 882 x 3-minute singles [7 x 3=21 mins x 126=882] on the
Target audience and
the late 1960s and early 1970s, some machines were used to play non-stop music at private
parties. You didn't have to bother about changing records every 3 minutes (singles) or 30
minutes (LPs), and some hotels and pubs bought machines for playing endless piped music in
foyers and other public spaces.
Another unique feature of
the tape unit is that its tape (drum) automatically rewinds after reaching the end of a 22-minute
track, or earlier, if it comes to the end of a recording. Having played track A1, for example, the
tape unit automatically switches to the next track (A2), rewinds the tape, and then plays that
track. At least that's the theory... (see Common faults).

Historic, very English radio
I was interested to find out what 1960s/70s music and radio programmes had been recorded on the
tape. Sector A contained much jazz and some classical music. Most of Sector D had been used
to record Round the Horne, a popular BBC Sunday
afternoon radio show (genre: camp comedy) featuring Kenneth
Williams and Kenneth Horne.
The radio show attracted 15 million listeners each week during its heyday (1965-69). In addition,
there were several recordings of the popular Goons
Show, featuring Harry Secombe, Peter Sellers and Spike Milligan.
found a live recording of the 498th edition of the Saturday
Club which I discovered was recorded live on 20 April 1968, based on a reference to
the "upcoming 500th edition in two weeks time". (This helped date when the music center was
originally purchased). The Saturday Club was a teenage pop-music show on BBC Radio between
1958-1969, and attracted audiences in their millions, and many of the big bands at that time,
including 'The Beatles', were invited to play their music live on air.
Classic 60s/70s pop
also contained many classic pop songs from the 1960s and early 1970s, including Homeward Bound
(Simon & Garfunkel, 1966), House of the Rising Sun (Animals, 1964), Nights in White Satin
(Moody Blues, 1972), Can't Get No Satisfaction (The Stones, 1965), Sundown (Gordon Lightfoot, 1974)
and Good Vibrations (Beach Boys, 1966).
A number of the tape sectors contained no recordings whatsoever, and would be useful for making new
recordings in the future. Because of the 'playback embargo', I was only going to find out what else
had been recorded after the machine was repaired.
In search of a radio
This electronic time capsule
really needed to be repaired. If I failed to do this, I could never discover what else was on
the tape for fear of inadvertently shredding it, nor could I fully use all the machine's
functionalities. It cried out to be preserved for posterity.
To do this, I would need to find out whether there was anyone who
could repair such a machine, someone who had the necessary skills to repair
the complex mechanical and electrical
operations of this 40-year-old 'time capsule'.
This was going to be a tall order. Or so I thought.
