Until today, I had not yet the luck to locate a properly working Sanyo RP-8880, so You might find a need to examine the innards of the set, when You manage to acquire one.

Chassis disassembly

  • Remove the 6 cabinet fastening screws from the back of the radio (in all four corners, in the middle in the upper part and in the middle below between the battery and mains cable compartments.
    Remove the additional screw in the battery compartment.
  • Take away the back cabinet cover and unplug the antenna connector.

  • Remove 2 screws from the rotary ferrite antenna, rotate the antenna for 90 degrees and remove it, unplug the connector of the rotary antenna.
  • Unscrew the screw near the + connector of the battery compartment and the screw at the left on the main PCB, remove the battery holder. Unscrew the red marked screws from the main PCB.
  • Unsolder or release the brown earth wire coming from the middle speaker connector which will pass near the battery compartment.
  • Remove all knobs of the rotary switches and controls on the front panel,
  • now You can flip the chassis with the main PCB to the left side.

Reassemble

  • Fit in the chasses, mount the battery compartment.
  • Put the rotary antenna in it's correct position rotated 90 degrees, plug in the connectors and mount it with two screws.
  • Remount the chassis to the front of the cabinet with the red marked screws,
    completely turn in the "feet" of the cabinet! the try to put the rear cover in it's place.
