Afternoon all..

I'm looking to replace the leads on my TS-505D/U vtvm set and unfortunately, I can't seem to find a reference to what wire gauge was used.  Oddly enough, the TM for that set does not have a parts list at the rear of the manual so I'm guessing here at this point.

Can anyone make a recommendation to a suitable replacement, preferably in the red-black-green-blue and rated to the 1000vdc that the originals were rated to?  Something like EPR for the jacketing material would be a bonus.  Double bonus points if I can buy it by the foot and don't need to buy 1000 feet of it ;)

Thanks again, as always
Reuben
