- A couple of days ago, we uploaded a video demonstrating a disc record pick-up arm of about 1930, called the Meltrope. Several appreciative comments were soon received, and one person, Chris Grant, enquired how they might connect an old pick-up they possessed, directly into their PC. They asked if I might make a short video showing how this could be done. This was a good suggestion, and this video is the result. Of course, there are many pitfalls in such a project; but it is hoped that this video will give a basic outline in how to get audio directly into (& out of) a PC. We emphasise that we are not an expert on computers, and though we have fun with old-time record-playing equipment, we cannot guarantee that it will work for you; still, it may be of some help. We certainly hope so! The disc we briefly sampled was previously used, 6 years ago, on another video, so if you would like to hear it complete, the link to that video is: • muddy water . I have not watched it again until tonight, so make apologies for the dreadful video quality! Still, the audio comes over fairly well… In addition, on our old website, there is a long, rambling web-page devoted to early U.K. electric pick-ups:

As always, a great video...you're such a talented teacher Norman! Sometime - when you've got nothing better to do - I would love to see you teach a series on the construction of a single tube HAM transmitter. I think it would be a great companion piece to your excellent crystal radio series...some of the best teaching on the subject!
All the best to you and yours Norman!

Way over my head, but whatever you say tends to draw one in to observe what's going on and you make it so understandable. What a talent!
Great info Norman. Always enjoy all your vids brother.
I wish I would have made a list of the vast collection of radios that had come up for auction at a local venue 3 years ago.. I had made the auction on the third day of the liquidation and was astonished at the 1/3rd of and acre lot of tubes, radios, parts, speakers, et al... Not mentioning the comments of patrons of the sale that stated time and again to me "You should of seen it the first day"! According to the auctioneer the estate was nothing but antique radios, horns, parts, sets..etc . etc... I was disgusted that I had not found out about it far sooner... I saw an early prototype speaker go for 1400 dollars U.S. .... and even heard murmurs that the particular item was worth 1800 or more in the crowd given the "right" buyer... I am a novice and have a basic understanding of the hobby, but admit I am an avid watcher of your vids, thank you sir for your time and knowledge...
Wow!. Thanks so much for taking the trouble to do this video for me. I have never been mentioned on CZcams before.! It is easy to connect once you know how. I use audacity so am familiar with audio software. I will let you know how I get on. I have an HMV 157 so will have to jury rig the tone arm as the pick up connector is the same diameter as the tone arm. Once again many thanks for you kindness. Chris from the good old Isle of Wight!
Norman! Thank You! This is what I ask for back some time! This is AWESOME!
3:12 For reference the black and orange sockets are for rear surround and subwoofer/centre.
Many thanks for the info! Cheers & stay safe... Norman.
Looks as though you are in need of a cheap audio oscilloscope... There should be suitable software which would be able to make your PC display waveforms with accurate voltage and decibel levels. Audacity displays the latter, and could fulfil your needs, providing that you can match the impedances closely enough.
Incidentally, and since you mentioned the name, sound systems on fairground rides are still sometimes referred to as 'Panatropes' by the more traditional fairground families. 'The Panatrope killed off the fairground organ' is still a current lament. The old Brunswick name lives on! Thanks Norman.
Excellent video. I believe the other two sockets may be digital or surround sound.
Listened it again today, with better speakers. Thanks again, Norman. Is it worthwhile adding some equalisation to a record and pickup of that vintage? If so, then what do you normally use?
You mentioned Audacity. It is the go-to, cross-platform audio-editing application here, and is being used in various flavours of Linux and MacOS. Audacity can also convert tracks to mono, as well as edit clicks. You can also zoom in very closely and edit out noise manually. Various bandpass and notch filters, plus graphic equalisers with different capabilities are also available.
One feature which is in use here twice every week for processing spoken audio, is the ability to select and amplify sections of audio semi-automatically, meaning that a suggested amplification level is pre-selected. You can choose to allow clipping, which it does very softly, to over-ride the suggested amplification level. You can also insert silence, remove general noise very nicely.
Some very good results can be obtained, even with mediocre sound sources. One which worked very well was the processing of a cylinder recording of a banjo and guitar duet, which, after editing, had almost no audible noise, and a very true sound (for the technology) of the instruments, and with no audible processing artefacts. One trick used for that was to sample out the noise, then invert it, and add it back into the audio. That worked extremely well, with no audible detriment to the music. Shall try to find it, and send it to you later, if your e-mail address from last year is still valid.
Hi Norman I wonder if you could answer me this question ? is it safe to use WD-40 on Bakelite and if Bakelite is exposed to WD40 for a long periods of time does it damage the Bakelite, do you know thanks.
Long time, no hear. Are you O.K., Norman?
Hi there - very nice of you to write! Yes, we're fine - hope you're the same; we've had a couple of quite big projects. A wax disc 'home recorder', vertical cut, from about 1925, and also we knocked up another electric cylinder player, which 'sorta' works OK. Both of these deserve a video - must get round to it! We've also being doing some smaller projects, like early microphones - really like the David Hughes 'carbon pencil' mike. Just needs really fine adjustement to set it up OK. All the best for now, take care, Norman.
Where do you find all these pickups?
John Wascavage I would like to know that as well! I have never seen one “in the wild “ as they say, in my stomping grounds of Maryland and Pennsylvania. Best Regards as always! David
