Dont go only by the picture on a Sams, its the guts
that matter. They only show one of often a long list
that use the same chassis. Never saw much Wards but
Sears 4 digit model numbers were USELESS.
You can also look for an EIA number on the PCB & maybe
find who built it. A few pictures may work also. A TV is
easy to ID that way but radio would be a challange.
