Hello, I hope somebody here can advise me on this problem. The individual that sent me my Edison S-19 did so with the horn attached. As a result the upper brace has been broken free from the horn. I examined this and found what I think is that old fashion lead solder was used to join the two parts together. Here is a link to the photo: s361.photobucket.com/albums/oo58/wmbuchanan/?action=view¤t=S19Motorb-1.jpgI would love to hear from others on this problem. Please let me know if I am right. Thank you Bill Buchanan |

I'd paint both surfaces with soldering fluid, and try to reheat the original lead to make the join.
I had the same thing happen with one of my machines, and I gave it to my father-in-law to fix. He cleaned the old solder off and reattached everything, but it wasn't in the exact position as it was and it threw the reproducer out of whack. (the reproducer got closer to the record as it moved across, so the stylus wouldn't have been tracking the groove evenly)
I ended up getting another horn that had also come apart & resoldering it with what was there.
Because the reproducer needs to move across the record perfectly level, I found it easier to use the marks left by the break to keep it in perfect alignment, rather than hoping the alignment was spot on & not knowing the exact position they were originally in.
I soldered the tube first, and then the horn mounts, making sure they couldn't move while I heated the solder with a small blow torch. I prefer a blow torch for this kind of job because it heated the area much quicker, and I didn't have to touch anything with the tip of an iron & posibly knock it out of alignment.
You might have to remove the horn assembly so there's no pressure on the joins to move them out of position.
Someone else might know a better way, but it worked for me & has lasted about 10 yrs so far without any further problems.

Matty,
Thanks for the in site there. I wouldn't have guessed it was quite so crucial to get it precisely where it was, but from reading your accounts I see where it is.

To be honest Bill, I'd put up with the dent.
You could mark & seperate the soldered join of the gold section, and have the dent pushed out, but it's still not going to be a completely invisible repair.
There doesn't seem to be any crease marks leading away from the dent to indicate it's been thrown out of it's original alignment. I would check the join below the dent though. The solder might have given way & it would not be an air tight seal. You could check by giving it a wash, putting your mouth against the join & blow to see if air passes through it. If it does, hit it with the blow torch & it should seal again. The dent itself shouldn't effect the sound quality too much hopefully.
The only other option I guess would be to either replace the whole horn assembly, or get a cheap horn off ebay that's missing the pivot rod & replace the gold plated section. Again, you'd have to align the replacement pretty accurately though.
Larry,
I didn't think it would be so crucial either until I reinstalled the horn, but it soon became obvious :-)
There probably is a slight tolerance that would be corrected by the flat spring twisting between the reproducer body & weight, but too much and the stylus is probably riding the groove wall on one side.
