I seem to remember seeing Radio-Craftsman ads in many post war electronics magazines such as Radio-Electronics, I believe that they were like Meisner where the majority of what they sold were aftermarket chassis without cabinets. So the cabinet that this chassis sat in was either custom built or an aftermarket one.
Anyhow the power supply is rather novel, it would appear to employ selenium rectifiers rather then using tubes such as a 5U4, as there is none shown on the tube diagram, and a power transformer as well. Most sets that I have seen with selenium rectifiers are series string, no power transformer, and use a pair of them as voltage doublers.
