Title: coax crisis
Post by: joesatch on June 15, 2024, 12:20:22 pm

i'm trying to wrap up a IIC+ preamp build and ran outta coax. i have some Mogami 2314 on hand. Anyone use this inside their amps?

No, but no reason why you should not do so.   You can let your customer know they've had a cabling upgrade.

For me, that's too thick for what I do as a routine shielded cable.  But it will work fine.

Hi Joe
Absolutely fine but may be a little large in diameter. I use in in SS Calibration type preamps.
My favourite small shielded cable. Cherish it, use it sparingly as Mogami factory shut their doors during Covid.

looks promising. how does it handle heat?  https://www.amazon.com/gp/product/B07L67VJDX/ref=ox_sc_act_title_1?smid=A1TE63QTMAEOQO&th=1 (https://www.amazon.com/gp/product/B07L67VJDX/ref=ox_sc_act_title_1?smid=A1TE63QTMAEOQO&th=1)

RG316 is my go-to coax.  See:  https://www.awcwire.com/rg-catalog/rg316-coax-cable (https://www.awcwire.com/rg-catalog/rg316-coax-cable) for one company's description.  Very well suited for hot environments. Should be impervious inside a guitar amp.

I've been using RG-316 for many years mainly because of it's resistance to heat. No oops while soldering.

Heat is no problem. The center conductor has PTFE insulation. And the clear/tan outer jacket is made of FEP. You would have to try very hard to make a heat mark on PTFE or FEP.

The RG-316 I have is fairly stiff and will not do tight 90° bends. unless tied down with cable clamps. Looks like the stuff kagliostro found is more flexible.
