Hey Boo, I am working on that now. As far as maint. it is pretty much the same as the SB as far as the
threads are concerned. I use a can of air to blow the center section(slide) out every now and again. No real scheduled maint. required. The contacts are nickel plated as well and do not require any special cleaning. I know some will be curious when they get them and take them apart

I ask that you not do that, there is no reason to. Some may never have to take thiers apart.
