[sdiy] Hammondparts

[Rönnberg Niklas]

Hi,

A friend has a Hammond Aurora with some problems... he found out that one
of the top octave ICs are bad. So he asked me if he could build a substitue
by himself. It's a 6-note top octave IC like this:

#Fig1a

On this page he can by a substitue for $39.95, but he insists on building
one. Does any of you any schematics or information to his help?

Best regards!
