- Demo of my AEG K8 Magnetophon playing Flat Foot Sam by Elmon Mickle (a very rare Elko blues 45rpm by the way). This rare machine is in great working order and uses German Telefunken vacuum tubes (EF12, EF14 etc.). It runs at 76cm/s (30ips) and is full track mono.
I'm looking for old AEG Magnetophon machines, if you have one please let me know.
This video itself sounds vintage!
Low bitrate audio and 4:3 picture... I do miss the 2000s.
That machine is probably more Hi-Fi than his camera
Yes the video have historical value, but must be in 720 lines and hifi record , because it's all about audio
76cm/s full track in 1948! Obviously mono, but audiophile quality!
Nothing like Analogical Sound
The machine sounds GREAT!
Stunning! Thank you for sharing this marvell of technology.
I've always wanted to see an AEG Magnetophon in action!
That definitely is a wonderful machine!
Beautiful machine.
The way the heads are set up it looks that the magnetic side of the tape is facing outwards.
Amazing high speed 76 cm sec.
Very smooth braking too.
Thanks for showing
Yes, the oxide layer faces outward. Ampex copied this format, including the speed, for their first recorder, the Model 200A.
Magnetophon tape recorders developed by AEG were designed outside of anything related to wire recorders. The 77cm/s speed was only implemented to increase the recording length. If it were possible to manufacture thiner tapes, believe me that the 1m/s speed would have last longer until the head gaps get thinger too. Maybe the wire recorders speed matches more or less the later tape speed, but this has nothing related. It's only a hazard. Telegraphones ran at 1,5m/s by the way.
Fantastic machine, even it's slightly bigger than an iPod :-)
Thank you for showing us!
@mkkiani Thanks for your comment. A minor correction though: magnetic tape is not a German invention. It is Danish: Poulsen Telegraphones existed in all forms in 1900: steel wire, metal tape and disc. However, the magnetic tape as we understand it nowadays (i.e a plastic tape coated with an iron oxide) is a German invention.
Thanks! The RFT MTG25 was made in 1956, so it is 8 years older than the K8 indeed.
very beautiful machine in great condition i liked to have a machine of this quality in my collection
Nice machine & great that it still works!
Beautiful machine! 8 years older as my RFT "MTG25" tape recorder by my "Lohengrin 8E 155" Music cabinet.
@videogamehistorian Thanks for your reply. It is an enjoyment to see this beautiful machine in working order.
Many thanks, keep it running
Nice looking machine, in good condition too!
These were used at broadcasting stations and also in classic Recording studios I think since it is a Professional Equipment...
Eduard Schüller ha a Laboratory @ AEG in the early Years first AEG K1 was developed, later on with Walter Weber AC-Bias Recording in Stereo. Where are we now ??
actually I SUSPECT the reason for the 30ips standard is because it was HALF the speed of the standard american WIRE RECORDERS - which (professionally) ran at 60 IPS.
It's not related to wire recorders. German recorders made after 1936 ran at 77cm/s. When Mullin captured two K4 machines, the speed was measured and found to be so close to 30ips that it was rounded to 30ips. Thus the standard high speed was born (and later often replaced by 15ips). Europe used that speed which corresponds to 76.2cm/s which is often referred az 76cm/s (just like 33rpm instead of 33 1/3 rpm).
lol, thats right. your that guys who played magnavox odyssey with Ralph Baer. Champion!
You're quite right. 15ips is the speed most often used in studios but 30ips is used for highest quality in the treble. This speed doesn't give better bass, quite in the contrary. The main reason of the original 77cm/s speed (which the Americans rounded to 30ips when building their own machines) is due to the much larger head gaps of the time (40 microns for the record head, 20 microns for the playback head) and also the larger size of the particles of the magnetic oxide.
merci, c'est super.
My english is very bad , but i see your Video many !
Its a very good old German Tape-Recorder.
My Gratelation to the great Machine.
Best wishes

Hello!
I own an K8 "Koffer" nearly like yours, and an T8 reel to reel drive, both must be restaurated. The T8 is now running again, one reel motor has been repaired, some shortcircuits has been repaired, maybe it would do his job again - when the electronic would be restaurated. In the Box there are missing some parts i don´t know how they look like. Maybe we can share some photos via email? I would be very happy to get it run again in some month/years! I´m very proud to have it :o) .
BELLISSIMO !!!!!!
Were you are based? Would it posible to visit you to look this beautys? That would so nice to see thay old recorder :)
my goodness!
Hi David, do you have schematic or service manual of T9u? The take up motor of my T9u has stopped working, Thanks Peter
Regards,
I am in the process of restoring a complete machine. Can you help me identify the tubes in the recording amplifier? Unfortunately, my copy lacks markings. I will be obliged for your help
Hi Mr Winter. I found a tape of Magnetophon AEG of a Bayreuth concert from 1956. Do you know what speed is need for playback?. Does it only playback in AEG or Telefunken machines?. Thanks
Does reporting mean, beside 30 ips also 15 ips?
well - where do you imagine tape recorders COME from? Yes - precisely - 30 ips or 77 cmsec-1 and by the DIN system the next adjacent speeds would be 15 and 60 or ABOUT 38 cm sec-1 and 154 cm sec-1 look it up.
do you own this?
Can tape player set up without tape going off the Reels. so far all videos i have seen are laying down
Could you also just post the music?
Вообще-то такой аппарат должен находиться в музее в Германии
