- PLEASE NOTE, that sorry, this video has a number of serious flaws in the tehcnical explanations. A new video has attempted to correct the,m, and can be see at • home recording 1932 EK...
This uis/was the original video description:
This ca. 1931 home recording device was, as had been all of its forbears, designed to fit onto a pre-existing gramophone.
That was OK, providing the gramophone had a motor with enough torque (= rotational strength) to turn every type of device.
Like most late 1920s home recording devices, it embossed a 'ridge & furrow' groove on a soft aluminium disc.
The one described in this video, I state that it was the first to employ the electrical system both for record & replay. This is almost certainly wrong, so I must apologise. I may have got other things wrong too, but hope you’ll overlook them as we take a quick tour of this early 1930s home sound recording device.
Best wishes,
Norman.
The early electric record players were some of the most overbuilt consumer products I have ever seen. The build quality is just absolutely astonishing. The motors were enormous. It couldn't be done today. It would cost so much money nobody could afford it.
"Take six!" In the 1930s, the engineers at radio station WLW used something like this to record samples of long-distance reception of their 500,000-watt signal (the most powerful in the U.S., if not the entire world, at the time). Unfortunately none of those discs were preserved.
So glad I've found your channel Norman ! Great! - Keep up the good work - so interesting! 👍👍👍
Why, thank you very much! Yes, there are others in the pipeline connected with early sound. Wishing you all success in 2021 - but above all - Keep Safe! Cheers, Norman.
I look forward to your videos of pre-war audio technologies, and watch them with great interest. Always fascinating and I learn from each. Thank you for taking the time to make these videos.
Man im just say thank u i watch u from buenos aires argentina love you channel !
Excellent video! The quality is pretty good considering the age of the equipment. Thanks for posting!
Great post! I love finding these records and digitizing them. The cardboard ones tend to be the most difficult to save!
It's surprising just how much has survived and has been saved. There are probably a lot of music saved to more modern formats but before you could share them with the world.
Fascinating to see.
Loving your videos, keep them coming. I think we met fleetingly at the Diskery a while back. I came down from upstairs with a stack of 78s, some nice finds too! You were quite interested in what I'd found, the staff had no idea what to charge me and when they said what they wanted, i was quite keen to pay and get out, lest they changed their mind!!! Hopefully see you again up there and have a more civilised chat. Stay safe
My grandfather bought one of these EKCO radiocorder devices in 1932 and proceeded to cut a large number of records featuring himself, friends and family as well as a number of BBC radio transmissions including royal messages, news broadcasts, dance bands, organ recitals, radio comedy and talks. I discovered the discs in 2016 in my parent's loft (no radiocorder) and have been recovering the sounds over the last few years (when I have time).
The BBC broadcasts can be heard at this link to my website greenbank-records.com/1930s-recordings#/samples/
I also have some videos on my channel presenting some of the more personal recordings he made at home including visits from his sister (from Alexandria in Egypt), his brother (a mathematics professor at Exeter) and an old friend (from Melbourne, Australia). Another recording made with his young nephews and niece after the outbreak of the 2nd Italo-Ethiopian War is a humorous satirical attack on fascism.
Thank you for recovering and demonstrating the device. I always suspected that the recording quality was never that good. Your recording example matches the best that I have been able to recover.
Awesome video Norman! A very interesting piece of 1930s tech, and the sound quality wasn't bad at all for a corroded disk! Glad to see a new post from you, thanks for sharing as always!
I understand John Logie Baird made television recordings on aliminium disks like these. He did not develop the technology to play them back, but I understand that has since been done with modern technology.
All I can say is, that's amazing.
Splendid music and audio tech. Presenter not too bad either 😆
Very interesting. I love old tech.
I would like to see a diagram showing how the cutting head works. I have a DIY lathe and cut grooves in old unused CDs .
As always, a fascinating video Mr. Field! In the introduction - as you're panning across your workspace - I saw many projects I'd like to learn more about. Would you consider making a short video that outlines the projects you're working on? I can't speak for others, but I think you could teach the phonebook and make it interesting!
Another great video, Sir and an interesting device. I noticed the drive trundle-wheel started to lose its grip as you got towards the middle of the recording due to the oil. Is that the trick then? Keep the middle dry and only oil the part where the embossing head will pass? Who knows? Looking forward to your next installment....
Hello Norman, great interesting video again!
I thought the recording sounded better than I thought.
Was the other in a lesser state than the one you used?
Couldn't you use plastic glass to record a record?
Hi Norman. What an interesting "little" gadget. It is most interesting to see a device from so early in the electrical era. I am more familiar with the later webcor home recorder that was usually a radio/phonograph combination. Did you do anything to the rubber parts inside the cutting head? I wonder if that would have made a difference to the quality? Stay safe, Enriko Kolesky
Maybe Dominion made their masters on an early version of this recorder :-) Actually your recording sounds better than some of the Dominions.. Do you know if any early cutting lathes have survived from the period? I seem to recall a story that the Oriole studio had inherited the Brunswick lathe, which languished in their attic, or some other dusty storage area.. Could it be the one that might have recorded early things like Elizalde, and subsequently avoided falling into the hands of Decca...
That was an expensive cool toy in the early 30's!
Have you tried covering the disk with a thin oil like kerosene before cutting/ engraving, I want to know what this process is like any chance of trying it cheers. What oil did you put on the disc? maybe a PTFE thin oil can you get or silicone oil watchman oil maybe. But you need to have a puddle of oil I think will be better not just a smearing. Better lubricant plus it acts as a damper
I think cork platter mat would work best cut down some of the noise give grip to the disc. You spoil us 2 videos in less than a month lol
Hoping you'd reply to this question I've got, I left you the same common virtually on the last video are they showing up. I thought you would be the man to know these answers or experiment with it
did you notice that when you was recording on the disc, the feed screw pulley with the rubber part on was slipping.
Do you know if there was some sort of switching device where one could record off the radio, and switch seamlessly to voice recording? I have a recording from Christmas 1944 that has a family discussing their Christmas but is bookended by what are clearly radio feeds.
An image of the kit at this link suggests there was indeed a switching device (labelled "G" in the image).
greenbank-records.com/1930s-recordings#/1930s-home-recordings/
In the image I had assumed the device was for switching between recording head and playback head (assuming use of two heads i.e. one with steel needle for recording and one with fibre needles for playing noting the soft and fragile nature of the aluminium surface). But perhaps it (or other switches) were used for switching between microphone or receiver. My grandad's recordings include several examples where he "seamlessly interrupts" a BBC radio broadcast (usually a humorous aside to try and lighten the otherwise solemn tone).
How popular were these devices, I know the RCA home recording system in the states at the same time was not popular at all because it was so expensive?
