Zero mA from multimeter...

69.111.108.237

Found my manual. Connected my multimeter to the biasing jack and turned on the amp but the meter reported 0 mA... adjust the biasing knob but still got nothing. Borrowed my friend's meter too and it also reported 0 mA.

Then I shut down the system, disconnected the biasing connection and connected my pre-amp to it. Turned it back on and there is audio...

Can anybody please help on why the meters reported 0 mA?

Thanks.
