Hi,

I've inherited an old 707 with a no adaptor input. The Roland AC
adaptor that came with it seems to have been soldered directly onto
the board at some point. The messy solder job has covered the marks
on the board and I can't tell which wire to solder back onto the two
points. One wire is black, the other has a white stripe along it.

Anyone know which way to solder these back on (top or bottom point
from the adaptor input on the board)

Thanks

Ryan
