Hi Henry,
Ultra 5.1 repair customer from Oct 2010. I have a hum that gets louder when increasing volume. I want to use the Ultra with an Onkyo receiver as a home theater. I bought 100uf / 105 deg C caps, but you repaired this system in 2010, so not sure if they're bad. It was unused for 10 years. Here are photos of the AC/DC power board. Not sure if any of these caps are bad? What direction should I go?

I apologize. I see that I did not seem to be getting notice, or seeing notice of some messages here. I do not have GMX subs. I have not worked on them, but may be able to help. Do you think you could remove the amplifier panel from the sub? I would likely need to borrow a control pod to test the sub after doing work.
