I have a UcD amplifier built similar to a schematic I found on the net with standard configuration of the tail pair. As I understand, it should be possible to control the on/off state of the amplifier by letting the bottom end of the tail pair float or not compared to VSS. For my amplifier, this causes one of the output devices to switch at some frequency - and thereby pump the bus at an enormous rate.
Anyone else had this weird problem with an UcD?
