I'm currently having ongoing issues with my LV-102 amp. I'm starting to understand why my parents didn't mind giving it up. After an undetermined playtime (it's random, sometimes thirty seconds, sometimes an hour or two), the amp makes a loud POP sound, and then all I hear is a humming noise, somewhat like a ground wire fault. The humming is inaudible before the pop, and the music is inaudible after it. Resetting the amp works sometimes, but not reliably. Is this a common problem, and is it worth repairing? How much do you figure it would cost?
The power supply caps are probably bad. The cost for the cap(s) will be under $50 and the cost for labor will likely run two hours or so. You can buy a new receiver with a warranty for not much more.
I guess I should mention you will probably have a difficult time finding anyone willing to work on this unit. Lux has no support in the US and techs don't care to warranty a unit that would have other twenty year old parts which are just as likely to break as the original problem.
