Good luck finding just the phase plug. Maybe you can locate a damaged driver and steal the tangerine from that. I know that bowtie found a loose tangerine for a driver of his that needed it, but I don?t know where he sourced it.

Otherwise, I would ditch the 808B, and just stick with the 802D. I like the sound of the metal phase plug better.

Maybe you could get one 3D printed....
