Hi there!
I am about to move my studio to another place, and I found
an old power amp (Alesis R-100) that it has this problem, I wonder
if I can fix it:
The right volume knob, when you turn all the way down, it continues
to let sound out, if I turn to other position he gets a lot of variations
on the volume level.
As you can see, this makes impossible to stay on a specific volume
level exactly as the left channel.
Is this a easy thing to solve?
And can I fix it or should I get technician help?
This amp has been for several years (2-3), in the original
cardbox, but with no use.
If this problem becomes expensive to fix it, I just might give it
away and get another one!
Any help or repair link would be great!
Thanks!

One of the most useful things that a studio can have is a stepped attenuating system for monitor level control. This insures repeatability. Were I in your shoes, I'd probably run that particular amp flat out, and go to GoldPoint or DACT and get an attenuator. I'd probably even calibrate it to RP200 as per Bob Katz's excellent instructions in his mastering book.

I am gonna open and try to clean it with a
contact cleaner.
Is this a correct procedure?
If that does not work, can you easy replace it,
or it involves soldering?

I'd surely try contact cleaner first. Yes, to replace it would require solder. The problem with some of the inexpensive gear is that it is not really easy for non-techs to replace parts, like it used to be. Sometimes it is very much worth paying someone else to do it for you.

Ok, thanks.
By the way, how did you manage to use your
own avatar?

If you look in your profile, you'll see that option.
