Hey all, when you rummage around in your parts supplies and junk boxes, keep an eye out for wither AVA10 or AVA53 RCA V cut crystals. I've managed to find 3 of them so far, but need 8 more to complete a set for my L-5. For quick reference, they are about the same size a a zippo lighter, but weight probably twice as much.
