I understand that they prioritize using an authorized service center for their recent professional equipment. But in this case, I’m asking for a helping hand — a goodwill gesture. This DAC has been out of production for years. It’s a small model that doesn’t have the same value as a Gold. I’m just trying to save time for the technician who will repair it. Because if he has to spend an extra two hours guessing component values, it won’t really be worth trying to fix it. Especially when you add labor costs on top. It’ll end up costing more than the DAC itself. So this is about avoiding throwing it away, even though it still works perfectly via XLR output. I’m asking for a bit of consideration…
And I was a reseller of the brand...Just black products.

Marc Lavry send me a reply with same information:Some companies do not give out any information unless you are a repairer with a registered business.
I have had full service manuals supplied by some companies after i explain who i am and what i am doing.
I have had No response from other companies under the same conditions.
I have experienced some companies that are 'unable' to provide any information what so ever after they were sold and bought by new owners.
Regretfully, our company policy is to not disclose our schematics or parts lists. We do not have service manuals to share either.
But even German's distributor
https://www.da-x.de
get any documentation.
But it is completely incomprehensible to me that nobody receives any information about where to send the lavry devices for service.
Is it perhaps like with smartphones or cell phones that after a certain age no service is offered anymore?
It was just to repair the headphones output. There were the references of the components on them but they burnt. It was written! But now, I am not able to read them. And they don't want to help me.
I read a lot of things about them... But it's worst in reality.

A further idea: ask various distributors for a replacement PCB of the head amp section.

The circuit appears to have horizontal symmetry (merge along the yellow axis). This allows for the identification of certain passive component values, as well as those of the two transistors, etc. I have marked in red the relationships between symmetric parts. Also, replace the OP27. This is probably the headphone amp of the DAC.
This may help, but it may not be sufficient if the root cause cannot be identified.

Personally I still think this is the best answer and the best way forward to my eye.
There are also some other resistors that look fried, but a test with a multimeter would show those up in a second.
I think it was the person I sold it to who burnt out the headphone output with a faulty headphone. But I refunded the money because I'm honest.
Ideally, I'd like to find someone to take photos of the inside of their DA11.
I followed your advices and did this BOM. But Lavry Eng doesn't want to check if I am right.
