JVC MXD 752 CD etc compact audio unit
Using 8V one motor powers the shift helical cam and the other moves drawer
and sub draws in and out and the CD deck up and down via a PTO linkage and
its helical cam. Limit switches work as well. Leaves just something wrong
with the mode sw or "cam switches" as JVC calls them. There is the matrix
for all those in the manual but to progress all that manually seems too
much.
