Wanted to share this morning's mod. I took a KL1 which a PO had upgraded to a P4, gutted it, and installed an 5B tint/R4 bin XP-G that I had laying around. It's driven by a single level 4x7135 board.

My proudest accomplishment with this is the copper washer that I soldered the board to and cut to fit in place of the old driver. So, here are some pics:
