MB6582 12V drops to 9V when SID installed (Solved!)

Hi. I built a MB6582 baseboard. I think it's Rev. 1. It's red, but it doesn't say what rev. it is, which leads me to believe it's 1.

The soldering looks good, but there's a lot of joints on here... :wink:

Boots up fine and connects with the SID V2 Editor.

I tried another PSU that I know works with another M6582 and get the same results.

I tried lowering the backlight on the LCD and that didn't change anything...

The voltage when the socket is empty reads 11.88V. When I install a SID it drops to 9.3V. And it sounds distorty. The 2nd SID slot behaves normally and sounds fine.

I've tried different SIDs and it's the same.

Hey ho,

If the same sid sounds fine in the second slot, there is likely to be a soldering problem somewhere and not a problem with the psu or the used power-option or the sid itself...

On this behalf, hi-res pics of the board top and bottom would be great ;-)

Bye,

Peter

On closer inspection it looks like some of the pins on the socket were pushed in some :rolleyes: . I carefully cut it out with a dremel, desoldered the remains and replaced it with a good socket. 11.86V! :flowers: Thanks for your help guys. I love the dummy idea. I'll keep that trick with me!

That solves this problem!
