I greet you! I would need the scheme of this "vintage" amplifier that needs to be "restored". The problem is that in the prefinal and final floor I have many "fried" resistors well, their value cannot be identified.I replaced the defective transistors: 2SC1509, 2SA777,2SB690 and 2SD 796 (each 2 pcs.) and the electrolytic capacitors adjacent to them. I could not go further because of the carbonized resistors that I do not know their value (I can only guess that they are values small, in the order of ohms). The schematic diagram I downloaded, from the address received by the kindness of a colleague is not complete - it is a single page (missing Q29-Q30-Q31-Q3 and resistors R115-R116-R117-R118 which are completely carbonized, at other resistors I could see their value).Thanks in advance!
Finally, I found the missing part
If stuck in the repair and you ask questions, please do it as follows: - Details: Give the exact model number of your device and the chassis ID (if there is). - If possible, please attach pictures of the appliance. - Anamnesis: Write down the exact symptom. If hard to describe the symptom, it is difficult to verbally defined clearly, attach pictures or sound of the phenomenon! - Tell what was you have done so far: search contact error, which parts has examined or changed yet, etc... The incorrectly named topic suspended and will be deleted after 48 hours! Suspended state while others are not able to comment until you correct the address. Subsequent repair of the defective title (within 48 hours) by clicking on the "Edit" tab can be carried out.
Pekny den,poprosim vas ,mate tento manual a servisnu schemu mam pokazeny impulzny zdroj standby 5 voltov,viete mi niekto pomoct,dakujem velmi pekne,urgentne.
Renault rádió kijelző: Borg 7700822081 hat pólusú csatlakozásának a leírása kellene. neten nem találtam.
Köszi. Gabi

Belefutottam, egy REVOX szallagos magnó rendbetételébe (A77), melyhez gazdija, (és én is) keresi a hiányzó hálózati csatlakozót. Kérem aki tud, valamilyen beszerzési forrást, ossza meg velem is, mert egyelőre beazonosítani sem tudom, ezt a csatit. Emlékeim vannak, hogy valami régi műszer volt ilyennel szerelve. A méreteket a csatolmányban lévő képen igyekeztem ábrázolni. Az érintkezők: 4x2 mm-ek
