My stereo speakers have little power

SOURCE: Yamaha RX-V861 Low frequency "flutter" after turning on

How close to your video monitor is this rxr? It is not shielded well as far as sync circuits in your TV are concerned. Refer to manual...accordianman

Hi there,

Thanks for using FixYa.

I would like to tell you its amplifier is not working properly. May I know with which you are using it right now (With PC or Television).

SOURCE: Very low speaker volume with all controls maxed

Problem solved... It's embarrassing to report actually. The A3 has a manual volume control knob which sits quite inconspicuous at the front RH side of the case. Just never noticed it...

SOURCE: Suddenly my speaker volume is low and scratchy

Congrats, you yourself is a good troubleshooter. Just pinpointed your problem. What you just diagnoist can be easilly checked just by taking other good known speaker. If that works your speaker is short check for audio output wires. If not your card needs replacement. If need further clarifications just comment.

SOURCE: Volume at 10 produces very low speaker output.!?

It sounds to me that all you are getting is the pre-amp stage of the amp and nothing from the power amp stage. As it is on both channels then it is something that is common to both. This could be something to do with the power supply of the power stage. Or whatever is on the heatsink. It could be that the amp uses a single audio amp IC for both channels. If it does my bet is that it's gone. If it uses two sets of semiconductors for the right & left channel it would be highly unlikely that both channels have gone, but not impossible.
