Rebuilding protank heads (NR wire required?)

[mekks082]

Well my wife popped her last head tonight and the local store was closed. I decided to give a rebuild a go. I used some Q-Tip cotton and some NR-R-NR ready made wires I use for my ithika clone.

The result was pretty good, I like it enough I might start doing this instead of buying the crap heads they sell stock.

I noticed the stock heads have a NR-R-NR setup but all the info I can find on rebuilding just uses straight wire.

Is it required? I have no issue using ready made wires but straight 30g would give me more freedom.

By using straight resistance wire, you do risk burning the insulator grommet and it might get a bit scorched over time, but I've never used non-resistance wire, and I'm still alive today

Keep your resistance above 1.8 ohms and the grommets shouldn't get too hot with straight kanthal. Just don't dry fire excessively. Mine are still doing pretty good after many rebuilds.
