Noone wanted to respond so I'll rephrase it.
I ordered a part #RF0496-1 front logo-pod volume control for my PSW650. The switch that arrived has a shaft-style volume instead of a thumb-dial volume. I spoke to someone in parts and they said they only show that one part# for some reason.
So my question is: is the thumb-dial volume front switch still available for the PSW650, or is it out of production?
