Kenwood KRC-794 TRANSMIT1, majd [ ] 1 felirat és semmi más
Sziasztok! A fenti autórádió előlapi szalagkábele meg volt szakadva. Próbára áthidaltam, de bekapcsolásakor a kijelzőn kb. fél másodpercig a TRANSMIT 1 felirat látható, majd [ ] 1 és semmi gombra nem reagál. Az SM-ben találtam Reset leírást, de valami Mask key-t meg Master key-t emleget, amiről nem tudom, hogy micsoda, hol van stb. Test módba beléptem, de itt elakadtam. Becsatoltam az SM-ből az említett részletet. Minden segítséget szívesen veszek. Üdv: Gyula

Ha vkinek volna rajza azt megköszönném, ha elküldené. Attila UI. tudom rajzot nem itt keresünk, de a helyén már próbáltam eredménytelenül, megpróbálom itt is hátha több siker lesz a vége. Üdv. Nincs senkinek tippje?
Trio-Kenwood: KR-3010 [Radio] S.N.962845 / Does not work, the final floor and prefinal floor defect with many burned component/

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
