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.
