Adcom Amp GFA-555 II hissing out of the right side..too old to fix?
My Adcom GFA 555 II amplifier is producing a slight hiss/static sound from the right side. I made sure by switching the cables, and swapping terminal contacts and its always the right side (red and black).
the music comes along with it, but its annoying to hear along with the static. You hear it most on quieter passages. It was coming and going, but now its heard all the time.
I guess i have to take it in to fix, but its 20 yrs old, and i worry about paying to fix a broken part, only to have another part fail a week later.
