Mike, I'll order at least two sets of the translucent knobs and buttons. I had held back expressing my excitement toward Stu's 4-LED knob board, because I feared that without a source for translucent knobs I would buy it only to have it sit in my spare parts bin. His last post on the boards indicated that he has ordered 100, which will surely go quickly if you end up sourcing the knob and buttons to complete the mod. Thank you for your interest in this project.
