I have and found most of the voltages as indicated on the circuit diagram, till op amp M 5218P; are near those specifed. The output on the centre of the two power transistors of both the channels are also alright.
While looking at the voltages on test points as mentioned on the page 7 for setting up quiscent current, these cannot be set.
Bit of history, the amplifier was lying unused for long time. Nothing in it has burnt. It was never opened earlier than this time, couple of days back.

While I was probing for voltages with DMM, with probe on collector of TR413 one of the fuses blew up. Later same thing happened on the other channel as well.
With the above as background can a Good Samaritan figure out feasibility of repair.
i am unable to upload service manual as file size is 7.3 mb
The Mission Cyrus 1 service information in the Internet did not include the PCB nor the voltages so far.
It is a bit difficult for you guys to repair it.
I have just repaired one and I took the time to redraw the PCB and measured the voltage to ease your job.

Üdv!
Keresem a fenti erősitő rajzát. Amit a kereső talál, az egy sokkal bonyolultabb erősitőé...
Köszönöm!
Közben megkaptam egy másik fórumon. Feltöltöttem ide is.
Sziasztok!
A képeken egy kb. két éves, SteelSeries Arctis 1 vezetéknélküli fejhallgató hangerőszabályzó potmétere. Ellenálláspálya árkosra kopott, cserélni kéne. De sem szervizkönyvet, sem ezen az alkatrészen egy tìpusszámot nem látok.
Valakinek van esetleg ötlete, merre lehetne elindulni a keresésben? Nem hiszem, hogy ne gyártanának hasonlót se már, de ha legalább a poti gyártójára ráismer valaki, már akkor könnyebb lenne egy katalógus alapján elindulni..
Ha valaki rendelkezik kapcsolási rajzzal / szervizkönyvvel hozzá netán, amiben fel vannak tüntetve típusszámok, természetesen azt is megköszönném!
