This ebay seller has a kit: BRAND-NEW-11-PIN-CABLE-FOR-HEATHKIT-HW-RADIOS-TO-HP-POWER-SUPPLY

I believe the seller told me he gets the wire from The Wireman e.g. "301. You might be able to use "302" but if you go too large on the conductors, you will be trimming more strands to allow them to fit into the 11-pin round connectors.

I just received one of these kits (a week or more ago) -- haven't had time to assemble it.  Maybe this weekend.  Seller was very prompt in shipping, and the parts look very good.  When completed, it should look very much like the original Heathkit cord.

What I don't like is the lack of strain relief but I guess you can create your own. There is another Amphenol connector that looks nearly identical, with metal strain relief, but they are rather expensive.

Bought some rotor cable from The Wireman several years ago. I was disappointed with it. The jacket was what I’d call semi-rigid. Unless I made sweeping bends with it, the jacket tried to crimp. On the other hand, the jacket on Belden cable was soft and pliable. Like I said, it was several years ago. Maybe his stuff is better now.

Thanks, I was aware of a number of places these are available, if you don't mind spending about $28 - $30 for two connectors.

Hook-Up Wire Suggestions for DIY Cable from HW-101 to HP-23 HV power supply.
==
As noted earlier, you can DIY build a cable with individual wires and then use
Cable Lacing, Heat Shrink, or Cable Loom.

BELDEN #8523 is a 20 AWG, 1000 V Hook-Up Wire, military standard: MIL-W-76C type MWP
https://catalog.belden.com/techdata/EN/8523_techdata.pdf

BELDEN #8824 is an Eight Color Roll Selection (25 foot spools), perfect for this usage.

Lost Skills and Knowledge: Cable Lacing
https://makezine.com/2009/07/28/lost-knowledge-cable-lacing/
Cable lacing was cable management technique before zip-ties, used in the telecom industry, aerospace, marine applications, and elsewhere. The thin cord used is traditionally a waxed linen. Modern materials used today in flat “lacing tape” include nylon, polyester, and Nomex.

Tecra Tools stocks a 9-ply waxed polyester twine that is suitable for the majority of applications.

I was never impressed with the wire Heathkit supplied with most of their kits... voltage ratings always looked a bit marginal.

I STILL lace cables in equipment. A skill learnt as an apprentice over 50 years ago, and with the advantage that unlike tie wraps, it doesn't bulk up the cable....I got two 1000 yards drums of waxed flat nylon cord at Dayton the other year for $2.

I believed the original Heathkit cable exceeded the cable voltage rating, but I am not aware of any failures. Two wires next to one another with 300 volt insulation each for 600 volts total would hold off 800 volts.
