NEVE 31105 schematic

[Sidebstudio]

I'm working on a NEVE 31105.
Have several variants of the circuit but not this with 2 presence bands.
So I need a schematic for this and I don't know where to find one.

I attached a photo of a couple of units.

Thanks!

31105 Pinout from Geof Tanner:

A = mic input +
B = mic input -
D = line input +
E = line input -
H = Pre-eq send (link to J)
J = Pre-eq return (link to H)
L= Post-eq send (link to M or fader)
M = Post-eq return (link to L or fader)
N = Gain boost (don't use)
R = +24v audio supply
S = 0v audio supply
T = unbalanced output
U = balanced output +
V = balanced output -
W = master mic/line control dc
X = +24v Leds/relays
Y = 0v Leds/relays
Z - chassis... make darn sure it goes to ground.


If I haven't listed a pin, nothing goes to it.


Make sure that the power supply can push out at least one amp... the bigger the better and is linear operation, fully regulated, with ripple and noise well below 1mV if possible.

Thanks for your answer but I don't need pinouts.
I need the schematic because I've to check values of caps in the 2 presence sections and check the inductors p/n.
I've measured each tap of inductors (one is 2H-1H-700mH etc etc the other one starts with 28mH to 200mH in 5 taps in total).
I can calculate them but would be better having original values.
I think it's a sort of mission impossible find an original schematic.
Thanks

No markings on the capacitors themselves?

I'm not working on an original unit. I'm building a custom unit for a customer mostly with original components (knobs, transformers, inductors) with a single mid band with multiple values.
I measured original inductors he gets and makes the math around them.
I have now in the workshop a couple of 33115 that measured different from the declared numbers on the panel / schematics. They have a single inductors for mid band instead of the couples in the 31105 (for low/upper presence).
It would have been helpful to see the values used in the original 31105.
However I'm testing the filter in the real circuit I'm building and at the moment everything measured ok with the choosen freqs.
