Hi Geezer,
The 531 is the high boy version of the 511 series. Check out this link for Radio Museum

The filter cap network of the 514 I restored was encased in wax, most are packed in black tar. Don't use electrolytic caps as replacements, use poly film caps of closest value. Be cautious with the brittle wires and take photos and draw diagrams. Be aware of a wiring change for the filter cap network.
