Adjust the bias VRs on the PA board until the idle current matches the exact milliampere value specified in your manual version (typically around 250mA per transistor pair, though values vary between the 100W MP and 200W Mark-V). 5. Common Troubleshoot Targets in the FT-1000MP

You need the (often called “Technical Supplement”) for repair or calibration.
