[Kenwood] TS590 low power output

[Steef PA2A]

Hi,

My TS590 runs fine again. One of the two final power FET 's was damagad. The service manual of the TS590 gives wrong gate voltages for the two RD100HHF1 FET 's when the rig is in TX mode. Kenwood says 0,44 Volts where it should be around 3,6 Volts when the bias currents are adjusted. So I first soldered out the wrong fet hi!

  Hi, my TS590 delivers only 50 Watts with the CAR setting at 50. Until a few months ago it gave full 100 Watts power at this setting. I did a full reset and only when I set the CAR to 100, the maximum, it delivers about 90 Watts.
  Has anyone an idea what could cause this problem?
