Tried 2 tested and working Return of the Jedi Pcbs. Everything works but no sound? Speakers make crackling sound when volume knob is turned. Only change is the AR II board. Where should I start?

Thanks!

Make sure that you have -5v going to the board. ROTJ needs the -5v for sound. If you know the ARII is good and the boards work fine, check the wiring and clean or replace the volume pots.

I just had my boards repaired by Elektron Forge (arriving today). Amongst other issues, one was a sound issue whereby I lost voices, but had sound effects. One of the Roms/proms/whatever thingies went bad, but they were able to fix it. If you've eliminated everything else, you might try shipping your board off to them.
 
Fixed tried several AR boards until it worked.
Jedi, does your Jedi work now?
 
Don't know yet. It's sitting in a box as I type. Gotta drop the kids off at school today and then give it a try. I also just did my first tube swap with the monitor in it and the convergence is slightly off. I'm going to have to see how bad it is with this game before deciding whether to keep it or not. If not, I've got a brand new monitor on hold with local413.
