Hello all,

I happen to pickup an amc 3050A integrated amp recently for cheap ($50,
MSRP is $399) but it has a problem and I wanted to know if it could be
an easy/cheap fix or should I just return it. When turned on it begins
to hum loudly once an output is selected the music comes out but it is
very distorted. I tried it with cd and phono with the same results.

Any thoughts? should I keep it try to get it fixed or should I just
return it?

Thank you for your comments, daniel

If you can indeed return it and get your money back, I would do so before
the seller changes his mind.

Agreed. If you are stuck with it, it could be the power supply main filter
capacitor.

or...... blown or shorted power output devices, etc, etc

All of AMC's products range from severely mediocre to atrociously bad in build
quality/reliability. I'd consisder it reason enough to return the piece of crap. For example,
on the well known 3030 tube output/solid state input integrated, it's horrendous enough that
the jerks solder the EL34 tubes directly to the circuit boards(enough to make me cringe by
itself), but they go a step further. With circuit traces on the "top side" of the board,
rather than making the boards with proper plated-through holes for the tube pins, they used
copper eyelets, which ensures that one or more of these eyelets will unsolder themselves from
the top side trace as you're soldering in the tube pins. Truly inspired bit of flagrant
stupidity. Just one example of how an AMC product will make you reach for the prozac.

Hi, ok I cannot return it the guy sold it "as is" untested, oh well. I
have tried using it as an amp and as a preamp with another integrated I
have and it works both ways. Still it does not work on its own!!

My assumption is that the problem is in the pre out main in. I have
tried with an interconnect but the noise humming is still there.
Anything I could do to fix it easily?

Thanks

My god! You mean that they do *not* use tube sockets!!? How cheap is
that!!?
