Wow!!!! Absolutely incredible repair. You have done wonders with this soundbox. No more buzzing, and you can hear improvement on the high frequencies. Many would have said this was an impossible task. You have patience like a saint! Amazing

Thanks 😊 but to be honest the soundbox seemed to fix itself. It's true there is a massive difference between the 1st recordings and the last, but once the rattle went, the buzzing went too, and that was before I openedit up! I thought it was worth dismantling as there was every chance the rattle and buzzing could come back again. Thanks 👍😀

Good work. I think the buzz has disappeared. When I did the no.16, I used Araldite instead of solder. Adjustment should be via the pivot screws with the lock nuts slack, then tighten the nuts when happy. I’ve heard of people using fine string around the edge when setting the gap. Don’t forget the 2x4 block of wood with the hole drilled down the middle to protect the stylus bar when working. Also, be careful of moving heavy stuff over and around the diaphragm, during work, don’t ask me why!

Thanks 👍😀. Yes I did think about using 2 part expoxy resin, but was able to buy some Alusol 45D cheaply and thought it worth a try. Glad I had the little gas torch though. I had no luck adjusting using the pivot screws. I ended up just tightening them up and it seemed to work 🤔. The rattle/buzzing I think was due to a loose bit of solder. Its possible it's still stuck under the spider somewhere, but I really didn't want to remove that so I am hoping it did fall out of its own accord. Anyway, prior to dismantling the rattle went and the soundbox effectively cured itself. I do have some recordings made in this state and haven't compared them to the final state, but I think in the end my repair was more of a service rather than a fix 🤔. Good practice for me though 😊

Incredible repair mate I am really so appreciative of the work you did, it now sounds amazing and will do an upload on it at some point... The difference from the first play is incredible sounds like a new box... The pivots gave me the same problem and I also had to re-tighten to get the needle bar to stop moving... Great camera angles did make it easy to see what you were doing and have now watched this twice over... Thanks again will always be grateful... By the way, what was the music you played at 9:30 I recognise it but can't put my finger on from where... Chris...

When the diaphragm was separated from the needle bar, could you simply have centralized the diaphragm in it's housing, (with new felts) adjusted the needle bar between it's two mounts, and then finally soldered the needle bar end to the diaphragm ? This would have ensured that the needle bar mount would have been correctly aligned to the centred diaphragm.
@mrrgstuff
2 жыл бұрын
In principle, yes and this is much what I was try to do. I did use tape to hold it instead of just fitting the back as it would have been very hard to ensure the diaphragm was centralised without being able to see the edges. Once it was soldered back in place I could have adjusted the horizontal position, however I hadn't figured out how the pivot screws were adjusted so just had to make do with tightening them up. For a soundbox which has tube gaskets, in my experience it is very hard to adjust the diaphragm centrally (and keep it there) before the needle bar is fitted, so a little bending of the needle bar is often required 😉. Thanks 👍😀

Some people will tell you that soundboxes, especially ones like this can't (or shouldn't) be serviced by amateurs, but we all have to learn somewhere and this one turned out fine (which was good as it wasn't mine! 😉😅). To be fair they are quite delicate and fiddly to work on. When you mention the spring, do you mean years of life or how many minutes it will play a record for in a single winding?

@@mrrgstuff I’m interested in knowing how many years of life. I did manage to buy a 127-C motor/spring on eBay and doge the extra £78 shipping to US by having it sent to my daughter who’s in London for 2 months. I’ll install it when she gets back as Ive had this pre-1935 HMV 102 that’s in very good condition except for the last 10yrs it lost tension in the windup and stopped working. Im doing everything I can now to preserve it. I thought while my daughter is still in the UK perhaps I should send her shopping for a backup spring and barrel (?) Perhaps you can recommend other parts that would likely go bad soonest that I can have as likely backups - as I can only buy a few! By the way, am I correct in thinking the pre-1935 models didn’t have the manual break to the left? Mine doesn’t have one. Thanks for your time - I won’t mess with the soundbox!

A good spring should last many years. It's not normally necessary to have a spare. There is always a small chance though that a replacement spring might be bad and break after only a few winds. You will only know for sure once it is in and working. There is not much else likely to break and other parts are small and light anyway so should be obtainable by mail order in the unlikely event you will need any. As for dating the machine, I don't know about the manual brake, but this thread might be helpful: forum.talkingmachine.info/viewtopic.php?t=24748 😀👍

It's a very good point. The final tweaking of the needle bar was probably unnecessary, but I thought it was worth a try with something stronger than my fingers. The other thing I didn't do was remove the spider in search of the loose bit of solder. There is a slight chance it is still in there, but there is no sign of it and I really didn't want to ruin the diaphragm. Thanks 👍😀

Great job, I think I lucked out just using regular solder! When I fixed mine earlier this year I seem to recall instead of using a jig I just assembled the diaphragm in the housing centrally, screwed it back together then did the soldering which seemed to work.

Thanks 👍😀. Very interesting link. I now see that I completely failed to understand the pivot screws, and that they are indeed adjustable. I suppose I was just lucky that tightening then up was sufficient. I think with the solder, provided there is a coating of existing solder on the diaphragm then ordinary solder will often be sufficient to join them. The Alusol 45D may make it easier, though a decent iron is certainly needed.🤔😉😄

I got a 102 in the mail on Friday with a 5B and it sounds a little buzzy on loud sections so I definitely ought to look at it. I have looked up other demos and I'm guessing that's not normal.
@mrrgstuff
Жыл бұрын
Yes, it shouldn't buzz, but over the years problems can occur and the sound quality can drop. The 5B (and 5A) are a bit risky to work on as they are made of pot metal which can degrade or swell and may crack or crumble unexpectedly. Also, unlike many other soundboxes the gaskets are not soft rubber tubing but felt rings. These are not so easy to replace and don't degrade like the rubber ones either, so may well not need replacing. The 5B in this video had suffered some obvious damage so it was felt worth taking the risk as it was useless otherwise. Something I didn't understand at the time is that the needle bar pivots are in fact adjustable. Buzz can be caused by these being too loose also.

I have also taken off the soundbox, shaken it, and it had no rattle so nothing appears to be lodged inside it. When I get the right size screwdriver I can look at it internally. The seller said it was in good working order and indeed the gramophone as a whole works very well. I just had to debate whether or not that sound on louder passages was normal.

It certainly can happen on loud passages, even with machines which otherwise are just fine. Do you know what sort of needles you are using? The thinner the needle, the quieter the sound will be, and using a thinner needle (sometimes called 'soft tone') can help
