Archon v 2.1 and 3.1 are easy enough to swap into, but the led module is the lipped type, not the flat standard cylinder as in other hilts. (Modular led system - MLS). Problem with the Graflex is that the hilt has an inner sleeve that the led module slots into and is tough to disassemble. Both cosmetic buttons need to be removed to access hidden set screws underneath. It would be much easier but more expensive to just have US do that work instead of you chancing the hilt getting damaged.
Removal of the Diamond card (WARRANTY VOIDED) & led module in many hilts I did not find difficult in the simple lineup from the v4 or v5 line. In actuality, the Archon style hilts are probably the easiest for me to swap out the electronic guts. Taking off the emitter and neck allow access to both the led module and switch. (I needed to replace my switch and the one I put in didn't even need to be soldered - it had 2 screw posts). The hardest part is loosening the hot melt glue US uses - heat gun or hair dryer will work for this.
Note - I did not have illuminated AV switches for the hilts I pulled the Diamond systems on. I didn't want the added complication of keeping track of the wires for those. Simpler to only watch those 2 wires for the basic AV switch.
Now, my advice: Either buy another Graflex CE and Archon with the Diamond system in both, or have US do the work for you. It's more expensive either way, but US knows what they're doing and have done this work many times before and it saves the warranty.
Info GREATLY appreciated!
I do have Illuminated A/V switches on both. Me being me, I'm not particularly worried about the warranties, I actually enjoy the challenge and resulting pride of doing the work myself. My concern was parts that would not be compatible or the like.
My plan, since I theyre on my wishlist anyway, was to order a diamond Consular and diamond Guardian, and swap the electronics. I believe the LEDs in all 4 sabers then are all MLS, correct? I would also order them with Illuminated A/V switches to make the swaps wire for wire.
