Best veroboard friendly coaxial cable?

Hi everyone. I'm about down to my last few feet of coaxial cable that I picked up at a local surplus shop a few years back. I tried using some other stuff lately to replace it but its either been too thick on the main lead and not easy to fit in a vero board sized hole, or the inner shield melts like velveeta once the least bit of heat is applied. this stuff I was using was near perfect, aside from having to shave a few hairs off the grounding layer if needing to feed it into the vero for grounding or whatever, it was perfect. Was made by alpha, and was grey with a similar internal shield that held up really well to heat, reminded me alot of the coax you always see in D*A*M pedals. Unfortunately, alpha couldn't source this stuff for me from what info I could give them and is likely defunct.

Can anyone point me into a tried and true coax that they prefer using? Would like to get into a habit of using coax for my ins and outs when sticking certain fuzz circuits in larger enclosures/weird orientations. Thanks everyone for any input you can offer.

Small Bear has shielded RG-174 and 178. Can't recall which I've used, but that's the stuff. May find elsewhere

I actually have some of the stuff that smallbear sells, i think its 178. its not bad stuff but not far off from the other stuff im looking to upgrade from. thanks for the suggestion though

Don't get hung up on "COAX". A simple lapped screen is all you need and it's far easier to work with. A coaxial cable goes to some trouble to align the conductor in the centre of a braided screen -  its often crimp terminated nowadays so the insulation is chosen for properties other than solderability.

That said, screened internal hookup wire is something of an alien concept at most suppliers - and I've almost used up the 100M reel I'd bought 30years ago. I just wasted time trying to find out what RS-components (one of the UK's biggest) offered and go nowhere thanks to a crap parametric search that offered a single-core with a screen but was no such thing.

In the meantime, raid old hi-fi RCA phono cables (the figure-8 stereo). That stuff works fine.
