Interconnects for SP-15 w/ EPA-250 arm?

Hi! A nice looking SP-15 outfitted with an EPA-250 tonearm and situated in an SH-15B2 plinth kinda fell into my lap. It's really striking, but I suppose the most shocking thing about it is the budget AT cartridge that's on the arm. I plan on substituting a Grace F9 cartridge that I have on another table.

The tonearm base has slots for interconnects, and I wonder what reasonably priced cables would be appropriate with capacitance in mind. What would you guys recommend?

Also, this new-to-me table doesn't appear to have a ground wire. Is that odd? I plan on having my turntable tech check the caps, pre-emptively replace/upgrade the MN6042 chip with the one from Fidelis Analog, and re-calibrate the table and all that. He should know whether or not to install a ground wire, just thought I'd check here first.

Thanks!

It appears that I have the stock configuration at the base of the EPA-250. Photo below, with a center hole for the ground.

I stumbled across the following image of a special matching cable hosted on eBay but I can't for the life of me figure out what it's called or where I might find it: https://i.ebayimg.com/00/s/MTA3MVgxNjAw/z/HO8AAOSwdGZcNY-3/$_1.JPG

If anyone who owns this tonearm can help me source an appropriate cable, I'd be most grateful! Thx

It’s proprietary. However, the ground connector is the same size as the center pin of an RCA connector. Use your favorite RCA cables on it (I’d use LC-1) and have your tech fashion a ground wire. I steal the split pin from an amphenol RCA for the adjustable tension.

The ground is the centre plug in the base. A pin pulled from a junk RCA will do the trick just fine with some appropriate wire soldered to it. Great arm, just superb. Ah, I see JP beat me to it... ;)
