I did extensive testing with amp on/off, eq on/off, a different microphone, as suggested. Differences are not dramatic. What seems to be going is that the voice becomes distorted past 12W at K3. Linear at 12W and scratchy at >12W. A bit better at 100W. I looked at currents with no signal. 1.1A in RX. 1.9A at 12W. 2.0A at >12W. High power turns on HPA, and it seems that the idle current for HPA should be > 0.1 A. At whistle: 3.5A at 12W and 20A at 100W. Ignacy
