"As easy as putting on a record"
I have always been curious as to how this worked in reality.
To "easily ?" use the record player amplifier for playback
and record would surely necessitate the use of a permanent
magnet erase head, there would be no oscillator
to provide the essential recording head bias to prevent
distortion on playback, or am i missing something ?
Someone please satisfy my curiosity.

I like it..would the other three speeds it plays at be 33, 45 & 78.
I'm sure I see a permanet magnet there somewhere.

Cheers.

Motors and valves "go wrong" ?!

There is one for sale in the thread about disposing of colleagues equipment.
Looks to be in good condition, and complete too.

Never owned one myself but I did tapepond { Correspond using tape .} with people in the 60s and the recordings weren't too bad. Usually speech and always at a speed of 3 3/4ips. Still see them for sale from time to time.
Cheap to buy if I remember.

PM erase, AC bias. Surprisingly good quality - some used the preamp with other decks for field recording. The only standard speed was 7.5 (78rpm). No fast wind as such - you used the supplied handle for that - but an ingenious bit of kit nonetheless. A creation of Alec Tutchings, main reviewer for Tape Recorder throughout the sixties.

There is one of those (well, there certainly was a couple of weeks ago) at a local 'antiques' place. It was in very good condition, but missing the microphone. Perhaps I should see if it's still there...?

They were also sold over here in Oz when I was a kid. I think they were advertised in our Electronics Australia monthly. Tim
