Hi David

two possibilities:
1.) an adaptor to the powerbus of the A-100

+12V--+-7809--+---o +9v
in | | | out
=== | === <-------capacitors are 100n
| | |
gnd---+---+---+---o

2.) or you pick the dc direct from the rectifier at the powersupply:

~+15V--+---+---7809--+--------o +9v
in | | | | out
=== ===c2 | c3===
C1--- | | |
| | | |
gnd---+---+----+----+--------o


All the best, Florian
