I've done a bit of google searching and I can't seem to find any repair logs or posts pertaining to my issue on this particular bootleg version, (maybe I'm just blind?). But I have a 44 pin Bubble Bobble bootleg board thats giving me issues with the sound. My first instinct is to replace the caps in the area of the volume pot, but I've got a feeling it's also the amp. Honestly I just don't know. I'd love to find the drawing set that I've been told apparently exists for this bootleg, but I was wondering if anyone else has had this issue.
As far as the issue goes, its not really weak sound, its just got an extremely loud buzz/hum over the speaker. Both the game sounds and music are present. Both the speaker and PSU I've been testing it is known good. Anyone have ideas, experienced this themselves, or have seen a thread someplace on this that I've just missed?
