After changing the High Voltage tap to ensure my full-load HV was above the 60V recommended in the manual for the KPA500, on-air tests show my signal is now absent any ringing. bell-like or otherwise distinctive sound. It is reported as sounding perfect.
Resolution of this issue involved ensuring proper supply voltage under load to the K3S as well as to the KPA.
