However, I can crank
up the volume to full, and faintly hear the audio


Sounds like maybe the tape monitor is engaged. Maybe nothing wrong worth
the
amp. Even if the amp does have a problem, the A-RV401 is a nice model,
worth
repair.

I understand your comment, but although I have engaged
all the input sources at one time or another, the faint audio
can be detected as from the source intended.

Yes. it has been a great unit. It was suggested earlier that
repair might be worth looking into, which I will. I'd hate
to just throw the whole thing away due to something small.

Thanks,

Gary



Then perhaps a failure of the regulated power supply area. You'd hear
nothing at all if the main amp was blown or if there were a large DC offset.
Could be one or more open resistors feeding voltage regulator(s) in the
power supply. Fairly common problem on similar model Onkyo receivers, though
I've only worked on one or two amps like yours, and it's been a while.
