This looks to be a well thought out design. "hot chassis"? Perhaps, but well isolated from the cabinet and the outputs are isolated by capacitors. I note the ground bus is insulated from chassis by the bakelite standoffs, and the front panel is insulated from the rest of the chassis the same way. From the look of the design, there shouldn't be any hazardous voltage applied to any point accessible from the outside of the cabinet once the cover is in place.
