I had a repair guy look into a bad headphone jack on my NL3 and he replaced the jack but it didn't fix the issue, so he tried looking for a schematic online but no luck. Is there one available and is it likely going to be needed to find the cause of the problem? Thanks in advance

I'm not aware of a schematic available online. You'd have to contact Clavia to try to get one. If you do, post it here!

A decent tech should be able to trace the headphone circuit pretty easily, though, that part of the board isn't terribly complicated.

Yeah, he's just a kid, so I guess I'll take it to a more experienced professional.

Not high hopes for getting anything regarding the NL3 from Clavia ...

check your email

Would love a copy of the schematic from anyone who has it. My NL3 arrives soon. I have the service manual, but there’s no diagrams in there.

have you tried to just Google search for it?

Yes - can only find the service manual with no schematics.

OK; there are schematic for NL2 in fact (which could also help as it may be similar as far as outputs section is concerned) but not for NL3 apparently, anyway: what is exactly the issue you have?

Ahh, if they don’t exist, they don’t exist. That’s ok. Just wondered since Mr Marko above said “check your email” to someone else, so I wonder if it had been shared before.

I only got my NL3 yesterday, but I like to have service documentation stashed away for gear I own. It actually does have some issues, none that will require a schematic though:
- PSU has wire links for voltage rather than switch, will have to solder to avoid using external step down transformer I’m testing it with.
- Multiple buttons don’t register or require excessive force to register, or double trigger. Shift needs to be held hard.
- Main encoder is damaged, super lose and inside the PCB on the back of the encoder is bent away.
- Plastic LED lens for Slot C broken off.
- Aftertouch response poor on many keys, likely deteriorated foam strip.

I didn't say they don't exist, I said that actually they are not easily found just by a Google search (and I don't have them), but you may try to PM Mr. Marko and ask him.
