Wire Question! Quick answer would be appreciated!
 

I'm a newbie so forgive me for this dumb question. My 1950 RCA uses 18 or 20guage solid wire throughout. Not thinking I went to Radio Shack and picked up the above. Before wiring my first Capacitor in I noticed the wire is only rated at 300 Volts. What do most of you use? Do you upsize to get a 600 volt rating? Do they make this smaller wire rated at 600 volts? Do you use the 300 volt wire figuring its as good as what was in there initially. I was getting real close to finishing up and wanted to be almost done this weekend but I want to be safe.
Thanx

I answered my own question by going to Antique Electronic Supply. I am ordering new wire now as well as the few Caps I have left. The '50 console will probably be on hold for a week or so. Now I can clean up the '56 RCA I just picked up.
