Hi! Thanks! Was indeed what I was looking for

Curious, what happend that rendered your power transformer dead?   I've never lost a power tranny even when things went wrong.

Yeah, it's really wierd.
So how it happend:
I trimmed the 24V -+ on the PSU.
Put it in the case connected the Channel PCB without any IC's or AMP in it.
Connected the VU meter en VU LED to the PCB and turned it on.
The LED of the VU went on for a few seconds and then went out.
I measured the voltage of on the Channel PCB and had nothing.

When measuring the resistance of the Primary windings, one of the two didn't gave anything anymore.

Please don't kill me, still learning a lot of electronics.

So, now with the Neve Calibration manual I'm trying it.

So everything is fine untill Compressor calibration, Limiter is tuned.

When I do a gain make-up on the Compressor, The signal on the output is not getting up.

Quick question for folk that have built this.

Which rotary switch did you use for the 24 step THD switch?

A bit late... but did you check the 33609 thread here?
Igor (RIP) did a great job... he was the first one to clone the 33609 if I remember correctly:

As with the other diy-racked kits support and manuals aren't great
my kit worked very first time and calibrated it with their v1 manual
i had to do it multiple times and used a little of my own feel because not
all measurements where able to get. but hey it sounds really great,
mine is loaded with carnhill transformers. dead quiet. creamy buttery soundwise.

Are you referring to the Threshold switch? 

I used what was indicated in the BOM... A ELMA 04-1130.  Is there a reason why you don't want or can't use this switch?  Arguably, this switch is on the expensive side, but it is quality.

Cheers!

At the end, mine is fully working now, it was an AMP340 with some bad transistors on it...
Matched the ZENER DIODES that I forgot to do.

Working beautiful as I speak.

The v1.1 BOM didn't specify a particular switch. I got a pair of a pair of Blore Edwards switches. But cheaper than the Elias and very sexy looking...

lennieh,

Ah, my build a v1.0.  Unfortunately, I bought my PCB's just weeks before DIY-Racked released their v1.1 update.

That aside, Blore-Edwards is solid quality.

Cheers
