Hello, Heath-seekers: I am fixing up a HW-99 here, thinking I'll probably put it up for sale, but have a question: Someone modified it for 80-40-20-15, instead of 80-40-15-10. No documentation, of course. Does anyone have any info on this mod? I wonder if I should undo it or just say the heck with it and leave it alone. Anyone have any thoughts on the matter? Vy 73, Tom
