Subject: [AH] Jupiter-8 part needed


I am looking for Roland part number 15229802
generally called: BA662A or B (I'd prefer the B
or 2 A's if that would work)

This is a VCA Roland SIP IC.

Roland US said they don't have any.

Any help would be appreciated in locating the chip,
a junk 052H270 module pcb, or other jupiter pcb with
the part on it.

Nothing like having one VCO out of 16 not working. :-(

FYI, this is a pre-DCB jupe.

Another question:  Does anyone know if this part is different
from the other 2 listed in the service manual...

BA662A (VF selected) white dot only
BA662A (Offset selected) color dot

I didn't quite get the difference.

thanks.
