Monoprice 5 watt chassis removal


Feb 5, 2018
Front Range, Colorado
Has anyone here pulled one of these from the cabinet. it should be simple. It has the typical four screws in each corner of the top and one on each side. With those removed, I get some up and down movement but it will not slide out. I thought it might be wedged between the cabinet and the top of the baffle and the cabinet but no amount of pursuasion gets it to budge. It's like it's still mechanically attached.

Any clues?
