I was testing out a QRX-949a yesterday (boy, did it sound nice).
However, when I got above approximately 1/2 watt of output, the unit started clicking in and out of operation rapidly; I'm assuming that it's the protection circuits. Turning down the volume stopped the clicking and returned to functioning.
The events occurred even if the speakers (Andrew Jones Pioneer's) were disconnected, or if 8 ohm 100w resistors were in place, and occurs whether the receiver has the back power connector set to 2 channel or 4 channel mode.
Suggestions on where to look next? I have not yet checked bias or DC offset.
