Hello,
I have come to find my DH is just missing the bulb socket mounted flush to the board. You can see in the picture the lower right one is there but the upper left one, L6, is missing. I believe this is the correct part: Wedge Base Socket - Sub-Miniature 24-8830

They are out of stock at PBL and BAA. Anyone know who else may have them or maybe even someone who has a few I could buy from them? Thanks!
