Lyrec 4755 Presence Filter

[Dark1]

I have one heavily modified/hammerepaired Lyrec 4755 active EQ module in my care. Anyone please have schematics or at least internal photos showing the original components in place? Previous repair technician (?) replaced (decades ago, apparently) all transistors, caps, removed transformers (if any), cut wires,... it's a mess. Many thanks!
