I knoticed you hadnt been around as much of late .
Very glad to see your getting stuck back into project work again .

Quite a lot to take in all at once from the schematic . I wonder is there an english translation of the 'theory of operation' of the circuits in the manual ?

I have original paper from the US K+H dealer. There was nothing like that. I think it’s the opposite. The schematics are drawn in an intentionally confusing way.

Actually, I'm sure it is drawn like this for the exact opposite reason of intentionally confusing:

The schematics follow not only the functional modules logic of the system, but also the mechanical way the unit comes apart for repair.

Note that identifying erroneous module for service is quite straightforward because of the modular/bypass setup.. (yes, I still keep a couple of these alive in our mastering room)

Only thing I miss from above schematics is marking of the ultra-precision, zero tempco caps

Paul made a great job at clearing the original schematics. Still it takes some work because of the switching.
The operation of this unit is also quite puzzling; high and low-pass filters with adjustable cut... huh?
We had two of those at Barclay studios. They were in the warehouse because no one really understood how to use them.
