Hello. I need assistance with a Rose RS 150B. A component has burned out and I need a circuit diagram (schematic), part name, or component markings to identify it. Where can I find technical support or service documentation? Any help would be appreciated.
You would have better luck talking to the local authorized repair service provider.
They would have the schematics.
Well, that 616 part looks burnt, but why? Was it bad quality part or do other parts have failed leading to 616 failure? You will neen a service manual with schematics to investigate.
But there is no public service manual, wich is a very very bad thing.
Audio brands with good reputation , like Revox or Sony, did supply us with service manuals to repair 50 year old iconic devices, like Revox B77 or Sony CDP 777 ES.
Will Hifi Rose do the same thing or will they become 1 of those very obscure brands 40 years from now? The choice is theirs…
Thanks, but I guess nobody wants to help. 
The issue is that no one really can help you.
Rose will tell you to ship it to an authorized repair center and Rose is the only one who has the schematics. Those are SMCs. I couldn’t tell you what they are.
Also you just show an image of the board and ask…what’s burned out. while you can see a couple of chips in the area… there could be other components that failed.
I’m sorry but ths is an issue w modern stuff. SMCs allow for smaller components and cheaper builds because it can be automated. But the downside it makes it harder to repair.
One fault has already been repaired. I only need the part number or marking of the component indicated by the arrow in the photo. The component is available and can be replaced, but its marking is missing because it was burned and damaged.If anyone has the same board and could check the marking, I would really appreciate the help.
Ich kann die Kritik leider nachvollziehen.
Ich habe sowohl direkt an Rose als auch an einen autorisierten Servicepartner in meiner Nähe geschrieben – ohne Erfolg. Keine Antwort, keine Hilfe. Mir wurde lediglich mitgeteilt, dass die Informationen zum Defekt „vertraulich“ seien.
Dabei geht es um einen Verstärker, der rund 4.300 Euro gekostet hat und bereits nach 2,5 Jahren ausgefallen ist. Nach meinem Verständnis sollte ein Hersteller oder autorisierter Service zumindest offenlegen können, welches Bauteil defekt ist, wenn die Ursache bereits festgestellt wurde.
Heute habe ich mit jemandem gesprochen, der den Kauf eines Rose-Verstärkers in Erwägung gezogen hat. Nachdem ich ihm meine Erfahrungen geschildert habe, war er sehr überrascht und hat sich letztlich gegen den Kauf entschieden.
Für mich ist nicht nur der Defekt selbst enttäuschend, sondern vor allem der Umgang damit. Gerade im hochpreisigen HiFi-Bereich erwarte ich einen deutlich besseren Kundendienst und mehr Transparenz.
Wenn der Service nach Ablauf der Garantie so aussieht, kann ich persönlich den Kauf eines Rose-Geräts derzeit leider nicht empfehlen.
Hat jemand ähnliche Erfahrungen mit dem Kundendienst von Rose oder den autorisierten Servicepartnern gemacht?
Translated the above for @danielllo71:
Unfortunately, I can understand the criticism.
I wrote both directly to Rose and to an authorized service partner in my area – without success. No answer, no help. I was only told that the information about the defect was “confident”.
This is an amplifier that cost around 4,300 euros and has already failed after 2.5 years. According to my understanding, a manufacturer or authorized service should at least be able to disclose which component is defective if the cause has already been determined.
Today I spoke to someone who was considering buying a rose amplifier. After I told him about my experiences, he was very surprised and ultimately decided against the purchase.
For me, not only the defect itself is disappointing, but above all the handling of it. Especially in the high-priced hi-fi area, I expect significantly better customer service and more transparency.
If the service looks like this after the warranty expires, I personally cannot recommend the purchase of a Rose device at the moment.
Has anyone had a similar experience with Rose’s customer service or authorized service partners?
How far would I have to take apart my RS150b to get to that part?
It’s hard to judge from the small image section.
I might be able to make some time for it this weekend.
Greetings from Germany 
„Hallo. Vielen Dank für euer Interesse und eure Hilfe. Ich habe leider keine Ahnung. Das Gerät ist bei einem Fachmann, der eine Hi-Fi-Werkstatt für verschiedene Marken betreibt. Er versteht wirklich etwas von seinem Fach. Vielleicht bekomme ich noch mehr Fotos, dann lade ich sie morgen hoch.“
We do not disclose circuit diagrams or component part numbers to any customers, including our distributors.
If your ROSE device has a hardware issue, please contact the authorized distributor in the country where you purchased your device to arrange for service.
When a hardware issue occurs, we do not replace individual components. Instead, we replace the entire board to ensure product quality and to protect our proprietary circuit design.
Hello. I understand the situation, and I no longer require your assistance. Perhaps other Rose users will be able to help me, because unfortunately I cannot rely on either your support or your authorized service center.
I am not willing to pay €1,800 for what the service center claims is a defective display, especially since the display started working normally again after just one week. This clearly suggests that the display itself may not be the actual problem.
As shown in the photo, the issue appears to be a very small defective component. Replacing that part may be enough to restore the device to full working order. A repair like this should cost no more than around €400, not €1,800.
I am very disappointed with both the diagnosis and the proposed repair cost. I hope other Rose users may have experienced something similar and can offer more practical advice.
First, I’m sorry you’re going through this. I can certainly understand why you’d be frustrated.
Regardless of what the ultimate root cause turns out to be, I think your expectations as a customer are reasonable. When a premium product develops a fault, customers deserve a thorough diagnosis and a repair path that is proportional to the actual failure whenever possible.
What stands out to me is your observation that the display resumed normal operation after a week. While none of us can determine the exact cause from a photo or from symptoms alone, intermittent behavior naturally raises questions about whether replacing an entire board is truly the only viable solution. It is understandable that you would want a more detailed technical explanation before accepting a repair approaching €1,800.
I also believe this highlights a broader issue that has been discussed on this forum for some time. Many of us appreciate HiFi Rose’s engineering and product design, but the post-sale support experience can sometimes leave customers feeling that they have only one option: replace an expensive assembly rather than explore a more cost-effective repair.
I fully understand HiFi Rose’s desire to protect its intellectual property and maintain repair quality. However, from a customer’s perspective, being presented with a repair cost that approaches the value of a replacement product—particularly when the fault appears intermittent—is understandably difficult to accept.
I genuinely hope another member has experienced something similar and can offer additional insight. More importantly, I hope HiFi Rose continues to evaluate ways to improve repair options and the overall ownership experience for customers who have invested in their products.
I, too, experienced a display failure on my RS130 that required replacement. Based on my own experience and the number of similar reports I’ve seen from other owners, I have become concerned that this may represent a broader reliability issue worthy of HiFi Rose’s attention.
This answer is very disappointing. It even says that Hifi Rose techs are not able to fix their own designs. Only able to change modules like monkeys in the zoo.
And about protecting you magical designs from copying, do not make me laugh.
Just fix failures for a reasonable amount or people will choose another brand.
The answer isn’t disappointing.
Here’s the situation in simple terms.
The RS150B is out of warranty.
The product can still be repaired however it has to be shipped from (?Germany/Poland?) to Switzerland where the distributor is located. They’ll do the repair work which will most likely be a board swap. Or boards. Then test it and ship it back.
They quoted a price which they will guarantee the work, yet @danielllo71 thought the price was too high and found a local repair shop who quoted him a lower price. The only problem is that the local guy isn’t affiliated w Rose and doesn’t have their schematics so that he doesn’t know the actual parts that were blown.
Now @danielllo71 is mad that Rose won’t tell him the components which were blown.
To be clear, Rose’s distributor gave him an option and he didn’t like the option and chose an alternative that was cheaper but held more risk.
I get it. But to dump on Rose… is that really fair?
Who is the distributor in Switzerland? Piega?
Yep, completely correct.

As you can clearly see in the photo, only one tiny component needs to be replaced. It is most likely the only faulty part in the streamer.
All I am asking for is the part number or its designation. Is that really too much to ask? I am not asking for circuit diagrams, repair procedures, or any proprietary technical information.
I simply cannot understand why anyone would suggest replacing half of the unit at a cost of €1,800 just because of one failed component.
At this point, the best option may be to wait until another Rose user experiences the same failure. Hopefully, someone will be willing to share a photo or identify the component. I would greatly appreciate that.
Otherwise, it makes far more sense to buy a second used Rose RS150B for around €2,000. For almost the same money as the proposed repair, I would end up with a second fully working unit instead of paying an unreasonable amount to replace a large section of the existing one.
