Hook-up wire (1000V 14A) PTFE

Super-thin PTFE (teflon) cable that’s rated at very high currents, various colours

If you’re looking for something better than PVC for the wiring inside your amp, consider PTFE. It’s a much more modern and high-performance plastic than PVC. The #1 benefit is that amp-for-amp, it’s far thinner than PVC insulated wire. (It’s also far lighter, which is why it’s so widely used in aerospace.) This benefit comes from its significantly higher melting point compared to PVC. This means a wire can carry far more current before its self-heating starts to melt the insulation.

 

In simple and practical terms, you can use a wire that’s no bigger than standard 3A-rated PVC wire for currents well over 10A. That covers any application in a guitar amplifier. The 14A PTFE wire shown in the second photo (right) is yellow and it’s as thin and manageable as the 3A PVC wire (green), but can carry more current even than the much thicker 6A PVC wire (red). The blue wire is the solid PVC wire. The downside is that PTFE wire can be a lot trickier to strip than PVC wire.
