Inexpensive reel-to-reel tape recorders, such as this Grundig reel-to-reel portable tape recorder Model TK 23L (Four Track de-luxe model), were widely used for music, as well as voice recording in the home and in schools. The Philips "compact cassette", introduced in 1963, later replaced reel-to-reel recorders for consumer use.

[edit] How it works

Please help improve this section by expanding it.

A tape recorder saves audio signals. The tape is covered in ferrous oxide (rust), which is magnetic. When the signal is fed into the recording head, the tiny magnetic particles are left in a pattern on the tape as it goes past. When the tape is played back the playback head can read the patterns and recreate the audio signal, which it sends to the loudspeakers.

[edit] Memories

Do you remember this tape recorder? Add your memories.

I remember using tape recorders like this in the 60s and early 70s to play pop music and comedy programmes recorded off the radio. My friend had one which she took with her to University. Most students then had a record player, a tape recorder or a cassette to play music in their rooms. By the late 70s we all had cassette players and hi-fis and didn't use reel-to-reel tape recorders at all.

I remember quite well this type of recorder,and really brought me nostalgic memories. It was manufactured in Germany in the mid-sixties. This was a four track machine taking 6- inch spools. It used valves: an EF 86, an ECC 81 and an EL 95 as a final stage. An EM 84 valve, referred to as a magic eye, used to emit a green light which served as a recording level meter. Sound production was sharp and clear, really superb when compared to other machines of the day. This was a very popular model. I think that these were the last taperecorders in the Grundig line that used valves, later models employed semiconductors in the electronics section. These machines were very expensive and the TK 23L cost around 50 pounds sterling, a big sum of money in those days -(a two months' salary paid for a good job).

My first tape recorder was a Grundig reel to reel manufactured in 1953 recording from the left reel to the right! It was very easy to set up, except for the 'magic eye' in which you had to watch the segments very closely so that you didn't over record. So simple, just plug into the mains; plug in the microphone; press the 'record' button and watch the 'magic eye'!! In 1960 I purchased another Grundig, which recorded both left to right and right to left, thus avoiding a change-over of reels.

ACCRA,GHANA My elder sister lived in Liverpool between 1963 and 1969. She came back to Ghana in Februry 1969 with a GRUNDIG TK23L TAPE RECORDER. This machine has since been working. The only part that has been replaced is the playbackhead.I wish to give it out for a token to be displayed in your museum. JULES B DANQUAH jefodanquah@hotmail.com

I still have my Grudig tape recorder and it still works. I purchased it in 1965 to record Churchill's funeral. The quality of sound is still very good but because I no longer have any of the leads which plug into the back I can only play back the tapes which I have kept. My mission is to try and obtain cables in order to transfer the recordings to a CD before the valves burn out!
