Hi everyone!
I'm helping a buddy figure out a problem with his Luxman M-120A amp. It has varied static and hiss in the left channel. Here's what I've done so far;
Cleaned all pots and switches with contact cleaner.
Checked and soldered any suspicious solder joints.
Removed the relay closest to top of unit, and cleaned all contacts. It was very corroded.
I've poked around inside the unit with a wood stick while it was powered on and none seems to change. The static gets louder and quieter at times, but the hiss is constant. Hopefully some of you has some has experience and advise on this amp/problem. Thanks
