I knew that the PT family (except Mini) was "compatible" with the BBE SupaCharger powersupply, that's one of the reasons I went w/the BBE over a Voodoo. Apparently, "compatible" in this case means "sort of fits." The mounting brackets screw onto the SC fine; perfect fit, in fact (this is the most important thing, I know). But, the SC doesn't fit flush against the inside lip of the PT. The IEC socket is mounted on the outside of the SC. It's plastic lip is bigger than the hole in the PT that it's supposed to fit thru. So, it sits about 1/8" away from the hole as opposed to flush. Not a biggie. The biggie is the fuse holder on the SC. It's placement on the SC's casing puts it about 1/4" past the edge of the second hole in the PT. If I want the outlet to line up with the hole (of course!) then the fuse holder won't go into it's corresponding hole in the PT. Bottom line: If using a BBE SupaCharger on a PedalTrain JR, it will have to sit about 1/4" away from the top edge of the PT and you'll have to bend the mounting brackets accordingly. This isn't a huge deal but it's worth noting, IMO. Anyone else run into this? Hope this post makes sense!
