Hello folks
I searched the internet for hours and the only source I've got wasgoodfellow.com. They only have 4N in 0.014mm PU-insuslated for 275Euro a single meter or 625 Euro for ten meters. If i can't find 6N
PTFE-insulated I'll try the above to repair my cartidge but maybe some experts can help.
Regards
Thomas

Posthorn,a wire of 0.014mm is very fragile and one with teflon insulation will make stripping quite difficult.Maybe this is the reason that many use soft and easy to strip insulations on such thin wires.

Hi Posthorn
You will find qood quality copper wire in the smallest Siemens relays. Where in the cartridge do you want to make repairs? In any case, if you want to just add-in a centimeter or two of copper wire from the armature to the pins, you will not hear the difference between 6N and any other thin copper coil wire. To join these very thin wires, make an ordinary granny knot in the add on piece, slip over the broken piece and pull tight before soldering. Set your iron at 350 degrees C, position the hot tip under the join and bring the solder to the tip from above so that the join becomes saturated with freshly fluxed solder. Only a second or two, otherwise, the whole lot melts.

To Panicos:
I have a broken Benz Glider (An Idiot called me burned the coils by measuring the inductance) an Ortofon MC10 Super with a broken wire close to the armature.
Stripping PTFE is easy with acid and water if you are fast.
To Bulgin:
Thanks for the tip but the thinnest Wire I found in relays was 0.04mm and the original wire in the Ortofon is 0.02-0.025mm. Do you have the order code for the mentioned Siemens Relay ?

Posthorn,you really have to be careful and really quick to try such a thing.Many years ago when I had my shop,I did this for an ortofon SPU,but the coil was cut close to the output pin.I used a 7watt soldering iron with machined tip to 0.6mm,and very thin solder which I sliced with a blade.Fortunately it was a one off try.For the Glider(especially)think also the possibility of sending it to Benz for repair,or perhaps van den hul.Good luck.
Posthorn,if you can find a useless cell phone earphone,or a useless microphone,maybe you will find their tiny wires useful.I don't know about their thickness but you could try.Removing their laquer should be easy with aceton.
Really, really thin wire can be obtained from the coils in cheap quartz watches, and the gizmos used for turning lights on and off at preset times.

Hi Posthorn
The coating on these wires are self-fluxing. No need to strip insulation As you solder, the stuff melts off. You could have another severe problem though. You say the break is close to the armature. You will find that your iron's tip will fly towards the armature without fail and attach itself close to the armature, coils and damper.
You will have to use a non-magnetic iron or otherwise use a gizmo to secure the assembly very firmly (I think it's called a 'factotum') before attempting this. If at all possible, attach some kind of heatshield between the armature and the job.
These little relays are packed away right now in an inaccessible place. I'll crawl in there later and let you know.
