A little oiling and a proper wind. Can my poorly HM 102 portable gramophone play a whole record - and what does its HMV 5A soundbox / reproducer sound like? #gramophone #78rpm #hmv #phonograph
Thanks 😀 👍. Yes I think the spring may be weak, but as long as it can play a whole side, will do for now. I'll have to get back to doing a full service on the motor at a later date
Is there an adjustment so that you can make the middle of the speed adjuster be 78 RPM? Because it looks like now you only get to 78 at the far right side of the speed adjustment arm.
To calibrate the speed control you loosen the two screws that hold down the plate on the motor board that the speed control lever pivots on, then you can slide it to the left or right, left for slower, right for faster.
Thanks 😀 👍. Yes, considering the dealer thought it would need a new motor, I think a good motor service is all it really needs. Cosmetically the machine is poor on the outside, however the soundbox is nice and clean and seems to work well
Dont know if i told you somewhere in different videos, but i reccomend (next time you plan to work on it) checking for any cracks in the horn, you'd be losing sound, if you Seal every hole that shouldnt be there, youd get much better sound
@@mrrgstuff anytime :-) there could also be something in the tonearm, Its easy to check by blowing into the horn, if you hear the air going through theres a leak somewhere, No air going through= OK
Yes, a blunt needle can do that. The needle should really be changed after each play. A dirty record or a worn record can also cause this to happen. It can also happen if the spring has weakened with age. Hope that helps 😀👍
That one I made myself, however here is a recent video I made comparing that to a couple of other options: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hLoFjPrpM1A.htmlsi=_gOxnuSzdqp8btPt Thanks 😀 👍
The soundboxes on these were often, maybe always made of pot metal, and this can swell, causing the fit to be tight. I don't have any direct experience with this problem, but if you can get the soundbox off, you may be able to see corrosion. You may have to take the rubber insulator off also. Be careful, though, as the metal may crack if you apply too much force. Good luck
@shosha1878 If its a No.5a or 5b like in the video, the top screw should unscrew (though I have never tried it) and the end of this screw is the pin which locates the soundbox on the tonearm. With this screw out you should be able to rotate it to any angle and also just pull it straight off. If the pot metal has expanded though, getting that screw out might be very tricky
That's a very good question, and to be honest I'm not entirely sure. 🤔 Some of my earliest ones are featured in this video though: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8Jl5AK4PvxQ.html I hope at some point to do a video covering more of my early ones, including the phonograph cylinders. Thanks 😀 👍
If they are US 78s then best not to as the gramophone will wear them quite quickly. UK and I believe European 78s are made of harder materials and should be ok. If you can though, use a more modern record player
