[AMRadio] Connectors

[DOXEMF at aol.com]

Hi Rick!
  I know exactly the type you mean.
They are made of at least twice the guage metal, tin plated copper, and are meant to be soldered not crimped.
 Still have a very few myself. 
 I would look for a Marine, Railroad, or other low voltage/high current supplier. The T&B yellow 10ga connectors are closest in metal ga. if US made. Most of the connector kits are imported junk.

Good Luck,
Bill,
