If not, you will have to troubleshoot on a component level, that is part-by-part.
Given its purpose, I suggest you live with its quirks as from your description,
it eventually does work. By the time you are done with it, unless you are exce
edingly lucky or there is a directly visible problem, it will likely not work.

Yea, it does eventually work, but it also will occasionally shut itself
off right in the middle of some music or something. There is no rhyme of
reason that it shuts off, but it does and all the LEDS and everything go
off. From what you described, I doubt I want to evne mess with it. This
is the kind of stuff I dont like working on. I may take a look inside,
but I think it's time to begin looking for another amp, and one that's
older. I prefer tube amps for an actual stereo system, but for a
computer amp, a decent older transistorized unit would be fine. This has
a radio, but I dont need it. All I need is a power amp with a AUX or
TAPE input.

I find it disturbing that Koss is out of business, I remember when they
were the top of the line for headphones.
