Saber sold. Thanks

resistors have no polarity along the current path, so they can be placed on the positive or negative side of the LED.
Resistors are important in any case. Check the resistor bargain section of the manual, if a resistor calculation leads to very small R value, use the drive to adjust the current in your led (skipping the resistor).
Also, the only real accurate way to determine your led Vf is to use a bench power supply, then run the calculation for the resistor. The Vf from the datasheet is just a ballkpark.

So just an update to this I think I might know what lead to at least part of the issue.

I based my resistors off the calculator on TCSS website, it suggested the 1.2ohm 3W they sell

My own manual calculation I got 1.2 Watts. It seems the store only sells 1.2ohm in 3 wattage so it was rounding up and why it suggested that.

While the resistance is the same I think the larger resistor was generating more heat, especially combined in a group with the positive wire connecting to all three resistors before they split off to each LED. I think this is why I had wires melting and resistors popping.

I am instead going to use 1.2ohm 2W 1% resistors to each Red LED, and this time skip a resistor to the White LED since it is only used for flash on clash. I'm also wondering if it would make any difference or sense to put one resistor on the positive of one red LED, and another resistor to the negative of the 2nd red LED. The Tri-Cree is wired in parallel. My reason to do this would be to separate the resistors with at least some space instead of being up against one another. as these are LED it shouldn't matter if the Resistor is on the Pos or Neg legs. If this idea is stupid, please let me know haha.

I have resistors and a new NBv4 on the way. I'll post more on the rebuild once parts arrive.

My goodness this classic beauty is gorgeous...

(one suggestion): post pictures with the clamp removed.
The clamp is hiding the crystal chamber details
