Ok, probably going to be posting about BK2K quite a bit as I start to give it it's second clean up and restore since I've had it - surprising how cruddy these things can get when you move house a lot and neglect them!
At the moment, I'm on a mission to remove as much of the speaker hum as possible as it's really bad.
Are there any tips specific to System 11B / BK2000? I've just pulled the audio, power and aux power boards and was going to replace all of the electrolytics that I have replacements for (and source those that I don't). Is this likely to help. I know it would with early Atari video games!
Mostly, this isn't noise from the lamps. Sure there is some noise that varies as the light effects change, but the worst noise is a constant low hum that is still there even if I disconnect all the power inputs from the interconnect PCB. I'm guessing that's general transformer / power noise. That's the only thing that makes me hesitate and ask about the electrolytics. I probably have replacements for all but the big caps in my parts bins already but I don't want to just waste them if it's not going to make the blindest bit of difference!
The manual also shows a mains line filter. I think I've got a spare one of them, is it worth replacing that? Again, don't want to waste it as my DE Star Wars needs all this too.
Thanks,
Martin.
[EDIT]PS: Game is otherwise fully working - no resets for instance.

I might have more somewhere, but I think I gave a bunch to someone else a while back maybe.
