To make a long story short, at the end of the PB assembly (DIAL button end) there is a protruding rod, spring and washer. This goes in and out as buttons are pushed and released. I discovered that when accidentally no buttons are pushed in, none can then be pushed in! If I reach in with something and nudge that rod into the assembly, a button can then be pushed in and all is well. That is until the situation arises again. For fun, a nearby mica cap looked like something to stop this rod, for whatever reason, from coming out too far. The rod is not banging hard into the cap, of course, just kissing it. Many repetitions of the cause (pushing a button in slowly so that the last button pops out before the new one engages fully) could not repeat the problem! This seems to work. Yes, I've done the normal spraying of the assembly and a removal of the assembly is out of the question, 40-190. So let a sleeping dog lie?
