  • Notes
  • This Knight model A9813 is a Farm Radio. It is presented in a new roll-top design table model cabinet. The chassis alone is A9815 and there is also a console, A9814 with this chassis and schematic.

    This model A9813 is very similar to the erlier model H9815 in catalog 1936 for 1935/36 - just having an other cabinet but the same chassis with probably the same schematic - followed by Spring-Summer Catalog 1937 as Knight A9724 with again the same chassis (console A9725, chassis A9726) but the schematic must be sligthly different to receive from 17 m instaed of 19 m and the cabinet was changed again.
