GENERAL INTERNAL LAYOUT:

The shell can be opened easily through four  standard screws:

We can split the OP PRO in 2 main sections connected by  a wide stripline:

1) DIGITAL SECTION & POWER SUPPLY:



2)
ANALOG SECTION + TONE CONTROLS







WELL ...now where to start ?   Of course I need a Rosetta stone.......

So I will pass tons of schematics in a way to try something will match a subsection
of the OP PRO ... in a way to start the decoding!


CHEERS!
