Doepfer

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
