Linear Amplifier Repair and Radio Repair for the Amateur Radio Community

I have begun to take on work in Linear Amplifier Repair and Radio repair for the Amateur Radio Community. This is a list of Amps and Radios that I have made operational repairs on during the past year. I have begun to incorporate solid state circuitry into my area of expertise and now can diagnose the RM Italy line of solid state amps.

  • Yaesu FT-101E Power supply resistor replacement.
  • Ameritron AL-811 Had burned traces on the power supply section of the DC side of the supply, Repaired. Installed new tubes.
  • Ameritron AL-811 Replaced Tubes and Tested.
  • Ameritron AL-811H No Transmit, High Input SWR on transmit. Tubes failed and four grid resistors were failed. All replaced with new parts.
  • RM Italy KL505 Solid State linear amplifier,  Failed, shorted power transistor. Replaced.
  • Icom 701 Receive and Transmit alignment was off. Re-calibrated as per service manual.
  • Kenwood TS-180 Output Amplifier sections.
