Any Idea when TEK might have started adding these pads that you speak of? I installed some new pass transistors in my RM506 and had to do some "creative" adaptations of the transistors that I was able to buy, Perhaps I was simply not seeing these pads on my unit? Or are these pads simply too obvious to overlook?
