• Notes

• The C87 was the first Australian radio to use a bakelite cabinet. There were two knobs at the front, volume & tunning and a regeneration trimmer control on the left side. The radio was advertised for  £17/17/- in 1932.

  A rebadged version called the Junior Four was sold by AGE.

  According to the AWA Service Data 1932, page 19, a later modification was to change the RF Choke to a centre tapped version with two extra filter capacitors added. Also a phonograph entry was added.
