What source do people use to replace the wiring in horn speakers? I looked at Radiodaze but did find what I was looking for.

I'm starting to think that jackpine is no longer in business. I sent them an email requesting a specific speaker cord 3 days ago and I have not heard anything in return. Not even an acknowledgement of receiving my email. They also have nothing currently for sale on ebay.

The basic issue with tinsel cords in general is that braiding machinery is required. The tinsel "thread" inside the cords is available.

I have forgotten, we have an ARF member who does have a braider FWIR was covering PVC wire with yarn..

The machines are available, used, any person with a mechanical background can get them going. The braider is not the only component, a bobbin winder or a wholesale source of yarn pre-wound to fit the bobbins the machine uses.

Most braiding for early radio was a 16 carrier machine, that is 16 bobbins. For a tracer, two bobbins in running the same direction consecutively are changed out for the colored yard. Over-braiding splices and back braiding lugs is a learned skill using and what is called a back-braid cone installed in the center of the braider plate.

The braider also has application making very flexible loop wire as well as custom and standard battery cable.

The overall issue is that there is not enough biz to support a commercial braider mill.

Labor being what it is, it can take some time to load bobbins, then load the braider, make a test run, adjust tension and the output to the take-up reel, then it is a matter of babysitting. The machine stops when a bobbin runs out.

There is a local mill that is flat braiding, absolute minimum staff maintaining some 200 flat-braid machines and an office, there are some 150 circular braiders of 12 carrier sitting idle.

I got to tour the mill a year ago in January. I watched with intent to try to discover if small lots could be done, it was quite clear that only orders that were acceptable were gaylord sized orders of hundreds of pounds of flat braid. Custom work was simply not cost effective.

So that leaves hobbyists to fill the gap...

Chas..

Well that hobbiest, jackpine, is 80+ years old so they are most likely done with the hobby.

I found rayon-covered parallel cord from Sundial Wire to be a close substitute. Just used some to replace the stiff cable on my Peerless Reproducer.
