• Can anyone give a quick answer to the length of ferrules needed for most amplifiers? I noticed on Amazon they mention a type A and typeB but don’t explain what the difference is. Other than looking at the pictures it looks like one maybe longer than the other. Other than the ones I’ve been looking at on Amazon does anyone one have a preferred kind? A kit would be fine but not necessary. I’m going with 8 awg because that’s the size I have on hand.
