Cartridge Wire Problem

Is this going ot be an isse?
Maybe

Will this affect the sound?
Well, if they ever touch it sure will!

Should I worry?
Never, this hobby is supposed to be fun!

Should I talk to the guy who did the work?
Absolutely. If you paid him a reasonable fee he owes you reasonable workmanship. It sounds like he was careless, lazy or blind.

Shoud I just heat shrink it and forget about it?
If you're willing and able okay, but those wires are incredibly delicate and they often need to make a loop or two to go from arm to cartridge. Will you be able to heat shrink them finely enough? If I were paying I'd politely request a proper rewire, but YMMV.

Sorry, no loose clips around here to weigh. You can always add a headshell weight or some weight on top of the headshell if necessary.

Dear Sector 2814: Don't worry about and do nothing that Doug recomended: this Doug has very little know how in analog audio ( he told in this forum that he has only 13 months on analog ), but he likes to be in all threads ( water of all glasses ) ,with not a single own contribution: it can't do it is an inexperience man, yet.
Sector 2814: use nail enamel on the bare wire, that's all.
Regards and enjoy the music.

Excellent suggestion Raul, IF he chooses to DIY a fix.

That's certainly better than attempting to heat shrink, which I also discouraged.

BTW, what color nail enamel do you recommend? I'm not much of an expert on that either.
