 Subject:       C8 and C9 occasionally fail due to oscillation

 Information:   C15 and C16 are added and the value of C8 and C9
                are changed to prevent RF oscillation and failure
 Procedure

  1.  Disassemble the amplifier and locate C8 and C9 on the main
      PA unit.

  2.  Remove C8 and C9 .12 uf chip and replace with .02 uf 500V
      ceramic (ICOM P/N 918-06119) keeping the leads as short as
      possible.

  3.  Add C15 and C16 .02 uf 500V ceramic (ICOM P/N 918-06119) in
      paralleled with C8 and C9.  Again keep the leads as short as
      possible.

  4.  Reassemble the amplifier and check for self-oscillation at
      full power output.
