Could be a couple things. Either there are a few limitations in whatever equipment you're using to listen to your x0x, or you are one of the very lucky few that have an AC line to plug into that is amazingly clean and quiet. Could be that your x0x is in an area with very little RF or EMF interference to deal with.Altitude wrote:I just tried this on mine with a switch and I cant hear any difference at all.. C11, C31 and C32 already perform that function and are more than enough, I suspect Jay has something else going on where more filtering is making a difference..
I don't know if this has been an area of discussion or not, but when talking about the TB-303 vs. the x0xb0x, I don't remember anyone saying anything much about the differences in the power supplies, and nothing at all about the difference in the TB-303 running on batteries vs. a 9VDC wall-wart.
At this point I'll stop and keep my mouth shut, since, while I've a lot of experience working on various power supplies, I haven't got a TB-303 to listen for a difference in battery vs. wall-wart, and TB-303 vs. x0x. Perhaps someone has.
