Any sources for continuous cast copper tonearm wire?

The subject says it all.

Has anyone located any upocc wire that can be used for tonearm rewiring?

Thanks.

Belden 9436, if it is still available. E

Thanks, but it is no longer in the belden NSN list.

It's also not UPOCC.

I have found upocc headshell wiring from "phono 1877" but no upocc tonearm stuff.

I'm guessing that they either don't make super small gauges or put in flexible insulation, but UPOCC was designed for miniaturization -- there should be plenty of light gauge wire.... Hmmm, maybe just not braided litz?

UPOCC was designed for miniaturization? I thought it was designed for marketing.

From what I understand, the lowered number of crystal boundaries makes it a less noisy conductor, which can be important in some miniaturized circuits.

[Steve Eddy]

The only noise to speak of would be the thermal noise of the wire itself due to its resistance. The only "research" I've seen on OCC wire indicates that it's about 1% less resistive than plain copper wire.

So if it's noise you're worried about, you could just use silver which at about 6% less resistance than plain copper wire would actually beat out the OCC.

I'm no miniaturization specialist or materials science guy. If you are then, fine. I agree.

[Steve Eddy]

What is your source for the claim that OCC is particularly useful for miniaturized circuits if I might ask?
