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.

„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.“
